Former Tottenham Hotspur boss Harry Redknapp has thrown his support behind under-fire Manchester United manager Louis van Gaal.

The Dutchman is under severe pressure at Old Trafford following a run of seven games without a win in all competitions, and it has been claimed that defeat to Chelsea on Monday would spell the end of Van Gaal's time in Manchester.

Redknapp has said that while Van Gaal's "decision-making" in relation to certain incidents has been strange, he does not believe that Man United's problems are all down to the head coach.

"Managers in football get too much praise when it goes right and too much blame when it goes wrong. It has always been the way but that mistake is compounded now by the fact that managers have so much less influence over player recruitment," Redknapp wrote in his column for The Telegraph.

"I look at Manchester United and, although there are some elements in Louis van Gaal's decision-making that we can all criticise, the bottom line is that he now has an ordinary squad of players.

"The biggest problem has not been the two managers since Sir Alex Ferguson left but the recruitment in a transfer market that, for the really world-class talent, has become dominated by Barcelona, Real Madrid and Bayern Munich. United might be the biggest club in the world but they have no divine right to win anything."

Van Gaal could reportedly walk away from his job at Old Trafford if his team lose to Chelsea.
