Manchester United manager Louis van Gaal has revealed his time in charge at Old Trafford will be his last in football . Van Gaal and his players head to Liverpool on Sunday in an attempt to solidify their current position in the top four of the Barclays Premier League . And the Dutchman has revealed his attempt to bring glory back to United will be his final challenge in the game . Louis van Gaal has announced Manchester United will be his last job before he retires from the game . Van Gaal told The Telegraph : ' I am old . This is my last job . For sure . ' I have to pay attention to my kids , my grandchildren but also to my wife . They deserve it . Now I can not pay that attention . I was not at the birthday of my grandson for example . I do n't like it . 'We have to qualify for the Champions League and we have many tests next year . That also develops the level of your team , and of course how many players can come in to improve our selection . ' Van Gaal has not had everything his own way in his first season in English football but already believes he has identified two future managers in his squad . The former Ajax boss won the European Cup with the Dutch giants against AC Milan back in 1995 . The Dutchman took charge of his national side at the 2012 World Cup in Brazil where they impressed . Van Gaal ( left ) was boss at Barcelona alongside Ronald Koeman and Jose Mourinho ( fourth left ) in 1999 . 'Wayne Rooney is very open to learn , ' he said . 'It 's amazing . I do n't know if he speaks with his wife Coleen about football , I do n't think so . 'But we have the process of talking here . Most of my players of my selection are open and that 's very nice . 'Michael Carrick is more or less a trainer-coach . He is also willing to talk about shapes and systems . The United boss intends to finish victorious before his spell at the 'biggest club in the world ' comes to an end . 'That 's nice . Rooney also . Not every player is very open and then you have to convince him , and then you get a struggle . It works or it does n't work . Give them time . Also give me time to do it . ' I am the most flexible manager you can imagine . When the players are coming with good arguments , I change my opinion . ' United head to Anfield on Sunday having finally abandoned the three-man defensive system that attracted so much debate earlier in the season . Despite using it all through pre-season and in to the competitive campaign , Van Gaal now claims he has settled on a more effective shape . ' I ask also the players which system they want to play , ' Van Gaal revealed . 'And then I ask individual players : 'What 's your favourite position ? ' 'First they do n't want to answer but now they are more open , and they answer . 'The fans are shouting it ( 4-4-2 ) . I have played it but that was to do with accidental circumstances . The system we play now is the system that I prefer , that I have played everywhere . The system against Tottenham last weekend is my preferred system . 'When it is needed , then I play with five at the back . Tottenham was 4-3-3 when we had the ball . When we defend it was more 4-1-4-1 yesterday . The next game is different . '
