Daniel Sturridge's season of frustration looks set to continue as he faces a race to be fit to lead Liverpool’s attack at Wembley. The England striker failed to train again on Thursday as Brendan Rodgers stepped up preparations for Sunday’s FA Cup semi-final with Aston Villa, meaning Sturridge hasn’t been involved in any outdoor work since before the quarter-final replay against Blackburn. Liverpool still have two more sessions before they travel south but Sturridge, who missed Monday’s 2-0 win over Newcastle United with tightness in his hip, would have to involved in at least one to stand any chance of starting at Wembley. Daniel Sturridge faces a fight to be fit for Liverpool's FA Cup semi-final against Aston Villa on Sunday . Striker Sturridge was left out of the squad against Newcastle on Monday after being taken off at Blackburn . It would even appear touch and go as whether Sturridge will be fit enough to make Rodgers’ 18-man squad, given how tormented he has been with fitness issues this season. Liverpool will give Sturridge every chance to prove his fitness but the signs at present are not encouraging. The injury is a continuation of the problem he sustained in the 2-1 defeat to Manchester United on March 22. Sturridge missed England’s games against Lithuania and Italy with what England manager Roy Hodgson called ‘a small tear’ in his hip. Sturridge admitted last week he will not be back at his sharpest until next season and he will be glad to see the back of this campaign, having missed more than five months with a combination of thigh and calf problems.

If, as appears likely, the 25-year-old is forced to play a minor role, it would leave Rodgers a decision to make with regards his starting line-up, as Liverpool captain Steven Gerrard is available having served a three-match suspension. Gerrard, whose 35th birthday falls on the same day as this year’s FA Cup final, missed several games in February and March with a hamstring problem but when he was fit for matches against Swansea and Manchester United, Rodgers decided to use him from the bench. He will be desperate to play at Wembley and Rodgers, who will be without cup-tied winger Jordon Ibe, must decide whether to keep faith with his current midfield of Lucas Leiva, Jordan Henderson and Joe Allen or alter his system to fit Gerrard back in. Rodgers will be without Jordon Ibe who is cup-tied having represented Derby in the FA Cup this season . Joe Allen says playing in these type of games is why he joined Liverpool from Swansea . Playing at Wembley will be a new experience for a number of Liverpool’s squad and Allen says a positive result against Villa is required to enhance their development. Liverpool are favourites to reach the final but the Wales international maintains there is no complacency in the group. ‘It’s the reason you join a club like this — the dream of competing for the top prizes and potentially getting some silverware,’ said Allen. ‘There’s a huge incentive for every player here. Villa had a great result on the weekend so they will be raring to go just like we will be. ‘That will make for a great game at a historic venue. Every single player wants to ensure we get ourselves back there for the final. Everyone is ready to make that leap. We are generally a young squad who are gathering experience and getting better all the time.’
