Liverpool manager Brendan Rodgers has experienced the harsh realities of his philosophies being called into question but unlike some critics he has no doubt about the credentials of Louis van Gaal to get things right at Manchester United.

When the pair last met back in December at Old Trafford United won 3-0, a result which bizarrely actually had more of an effect on the beaten visitors.

'The Premier League is different from the leagues he will have worked in before but I don't think you can argue with his credentials.

Van Gaal's Manchester United go into the Barclays Premier League match at Anfield in fourth position 

'There is no question about the philosophies he has put in place at Ajax or Barcelona or his achievements and when he leaves Manchester United he will still be one of the great managers.'

Rodgers found himself under similar scrutiny after Liverpool's poor first half of the season but things have turned around and he is flavour of the month once again.

He admits August to December was a tough period for him, when his methods were being called into question, but believes he has come out the other side stronger for it.

'It is at Anfield against a big rival and we want to win the game. I don't think the result will have an overriding factor (on the race for the top four) because there are a number of games to go but psychologically it can give you a great boost.'

Sure, based on the information provided, Brendan Rodgers believes that Louis van Gaal has established himself as a great manager and his credentials in achieving success with multiple big clubs such as Ajax and Barcelona are unquestionable. Rodgers acknowledges that the Premier League is different than the leagues van Gaal is used to managing in, but still argues that van Gaal's philosophies have been put in place effectively.

In terms of Liverpool's match against Manchester United, Rodgers mentions that they want to win the game but doesn't necessarily believe that the result will determine the race for the top four, as there are still many games left to play. However, he does believe that a victorious match against a big rival may boost Liverpool's morale psychologically.

Furthermore, Rodgers admits that August to December was a challenging period for him as he encountered scrutiny regarding his methods. Nonetheless, he claims that this hardship has helped him strengthen as a leader.

To summarize, Rodgers' statements indicate that he respects and values van Gaal's achievements, has deductions over the potential effect of the game on the race for the top four, and regards what he experienced last season as the sheer difference they've been through building-up him to be strong nowadays.
