... and Redknapp is also struggling with it
Queens Park Rangers manager Harry Redknapp defended his decision to play with three centre backs at Tottenham, but there are question marks over how effective the formation is in the Premier League.
Redknappâs QPR and Louis van Gaalâs Manchester United are yet to win a Premier League game this season after introducing the 3-5-2 system at their respective clubs.
Hull City have largely played with the formation for the last couple of seasons and manager Steve Bruce has so far enjoyed more success than Redknapp and Van Gaal with it in England.
Although their central defenders have not been performing particularly well, with the exception of Phil Jones, it is the wing backs who are causing Redknapp and Van Gaal the biggest problems.
Mauricio Isla suffered a difficult debut against Tottenham, with the White Hart Lane club constantly doubling up on his side with Danny Rose and Nacer Chadli. As a result, Steve Caulker was dragged over to the right, leaving Rio Ferdinand exposed in the middle.
Ashley Young has also struggled with the defensive side of his duties in a wing-back role for United and was caught out in the home defeat to Swansea City.
Redknapp admitted after the Spurs game that he has switched to 3-5-2 because Loic Remy does not like playing up front on his own, while Van Gaal appears to be trying to accommodate both Wayne Rooney and Robin van Persie.
Other than asking Bruce for tips, Redknapp and Van Gaal are faced with the choice of defiantly sticking with the formation or making a brave decision over their strikers

So if we are playing this formation to suit Remy (and not Ferdinand), what happens if Remy leaves?
