Gerard Pique has heaped praise on Barcelona's attacking trio of Luis Suarez, Lionel Messi and Neymar, claiming he has never seen a relationship like theirs. The Spanish giants are in France ahead of their crucial Champions League quarter-final tie against Paris Saint-Germain, and Pique took some time out to wax lyrical about his team-mates. Speaking to UEFA.com, the Spain centre back said: 'I've never before seen a relationship like the one between Luis [Suárez], Ney [Neymar] and Leo [Messi].

Continuing, and perhaps in a sideways swipe at the relationship between Gareth Bale and Cristiano Ronaldo at La Liga rivals Real Madrid, Pique said: . 'Being a footballer always goes hand in hand with a certain amount of egotism, but those three really do have a special relationship. In Madrid, there has been much speculation over Cristiano Ronaldo's (left) frustration with Gareth Bale . Barcelona are preparing for their Champions League quarter-final match against Paris Saint-Germain . 'They get on superbly. There's no hint of jealousy and that shows on the pitch.' Ronaldo's frustration with Bale has received much media attention over the last month, culminating in the Portugal star's non-celebration and apparent frustration at Bale taking the limelight to score a goal against Levante in March. Over in Barcelona, the Nou Camp's front three have a combined 88 goals between them in all competitions this season, and could add to that when they take to the field at the Parc des Princes on Wednesday night.
