I conducted a poll on my radio show recently, and more than 70 per cent of those who voted believe Manchester United will win the title next season. Is it heart ruling the head among the United faithful? Or is there a genuine belief that serial winner Louis van Gaal is about to re-assert himself at the very top again? Manchester United boss Louis van Gaal was left frustrated after his side were defeated 1-0 by Chelsea . Van Gaal poses for pictures with United fans at the training ground during a day for the club's foundation . Van Gaal (pictured talking to fans) is starting to assert himself at the United after a stuttering start . If he is to take United back to the very top, he’ll need more than Memphis Depay. I’ve already established in this column recently that Van Gaal is a great, and he is a winner. I love the fact he has set himself this huge challenge of resurrecting a fallen giant at the end of his career. The Dutchman knows, however, he will not be judged on his ability to repair the damage done by David Moyes. At the end of his (albeit shorter) Old Trafford stay, his record will need to stand comparison with that of Sir Alex Ferguson. Obviously Van Gaal cannot win the same number of trophies Sir Alex picked up during his 27 year reign, so relatively speaking what does he need to achieve to be considered a success at United? Sir Alex underachieved in Europe: only two Champions League wins in his time – just one more than Liverpool in the same period, and the same number as Jose Mourinho (who won those in significantly fewer years). Van Gaal has also underachieved in this department – his only Champions League win was with Ajax, not Bayern Munich or Barcelona. Van Gaal will be hungry to add to that success which came 20 years ago. He should target Euro success as soon as possible. Domestically, United still don’t quite look like the finished article, despite their impressive run in 2015. But they should at least be challenging for the title next season. So what needs to change for United to reach that level where they are in the mix to win the Premier League and the Champions League? Sir Alex Ferguson celebrates his second Champions League triumph with United in 2008 . Van Gaal celebrates winning the Champions League with Ajax in 1995 - his only triumph in Europe . Keeping David de Gea would be ideal, but Victor Valdes has winning experience and there is a bond between the former Barcelona keeper and the manager after their time together at the Nou Camp. Van Gaal blooded Valdes and then man-managed him superbly. Either keeper is fine, it’s obvious who would be preferred though. United need a quality right back – Nathaniel Clyne has been linked and the Southampton man would be perfect. If Clyne is the right fit, Luke Shaw needs to stay fit. He’s been like a rabbit in the headlights this first season, but he’s dealt with Van Gaal’s brutally honest management style well and put in a fine performance at Chelsea. I’ve said before, Shaw has the potential to be an all-time great at United. At centre half, Phil Jones and Chris Smalling might become the trusted partnership, or wisdom may win the day and United could go and get Mats Hummels from Borussia Dortmund. He’s a winner and a leader – perfect for United. Luke Shaw (right) has had a difficult start to his United career but impressed against Chelsea . Mats Hummels (left) of Dortmund is a player who has long been linked with a move to United . In midfield, United are strong in my view – Daley Blind and Michael Carrick can fight for that anchor spot, or even play together depending on the opposition. I can’t help thinking that adding another Carrick-type player to the squad might be a wise move for Van Gaal. United fans are seeing the best of Ander Herrera and Marouane Fellaini in this current period, while Juan Mata and Ashley Young have been big positives this season. Wayne Rooney’s quality and contribution as United captain is never up for debate – for me he should be the closest challenger to Eden Hazard for Player of the Year. Which leaves players like Adnan Januzaj, Radamel Falcao, Robin van Persie and Angel di Maria. Ander Hererra (holding off Chelsea's Cesc Fabregas) has impressed for United in recent weeks . Juan Mata (right) is starting to show his best form after moving from Chelsea last January . Angel di Maria (centre) has struggled this season but to leave him leave would be a massive risk for United . United's on-loan striker Radamel Falcao has struggled for form ever since joining the club last summer . Januzaj has stalled a little bit after bursting onto the scene, but he may yet come good. Van Persie would be brilliant off the bench next season – he’s still capable of scoring important goals. The two South Americans are expensive stellar players, but neither have impressed in their first season in English football. To let both leave would be a gamble – European rivals will pick them up, and if they suddenly re-discover their game, United will look foolish. Keeping both is also a risk, but one worth taking if you add one more world-class attacking player. And that’s why United need to go all out to get Gareth Bale. At times this season United have been so slow in their build up. Bale brings dynamism, goals and energy to a side. He could flourish at United, stepping out of Cristiano Ronaldo’s shadow at Real Madrid. United have already enquired about PSV’s Depay, he has all the skills and end product to be loved at Old Trafford, but United still need that marquee man to humiliate opposing defences at home and abroad. Memphis Depay (left, in action for PSV) is a prime target for United and has the potential to be a great signing . Gareth Bale has the dynamism, goals and energy that United have missed in their side this season . Van Gaal signed a three-year deal. If he wins the Premier League and the Champions League in that time he will be considered a total success at United. It’s a tough ask, but he could win both next season. Given his record of winning titles elsewhere, I certainly wouldn’t rule that out. I suspect the United haters will have to calm themselves down over the next few seasons. Did they really think United would be gone for long?
Man United have shown great promise for the future in recent matches . Louis van Gaal has a decent squad at Old Trafford but must add to it . Gareth Bale, Memphis Depay, Mats Hummels and Nathaniel Clyne on list . Van Gaal is a serial winner and can get United challenging for honours . Dutchman will want to leave United with record that compares to Sir Alex . READ: Liverpool launch bid to rival Man Utd for PSV winger Depay .
