Gerard Houllier believes Wayne Rooney
has "taken the right decision in his development" by opting to stay with Manchester United.[LNB] Rooney has signed a new five-year contract after previously indicating that he wanted to leave Old Trafford.[LNB]But Aston Villa boss Houllier admits contracts "do not mean a lot" since the advent of the Bosman ruling.[LNB]He cites the example of Cristiano Ronaldo, who was under contract but left Old Trafford for Real Madrid in the summer of 2009.[LNB]Ex-Liverpool boss Houllier said: "I don't know what happened really (with Rooney). I was impressed by Sir Alex's press conference because he responded well to the situation.[LNB]"It was not easy and he felt emotion which showed the liking he had about the player.[LNB]"I think in the end I would say, all (sides) win because I wouldn't imagine Rooney outside of Manchester United.[LNB]"I like the boy, I like the manager, it is a good club, and he probably made the right decision regarding contracts.[LNB]"But you never know what happens. Ronaldo had a contract as well and he left and when a player wants to leave maybe you can delay that for one or two years.[LNB]"It is not good when a player has nine or 10 clubs and this is why I think Rooney has taken the right decision in his development, whatever happens next year. We don't know.[LNB]"Whether Wayne has realised he can't play for Manchester City, I don't know."[LNB]As regards player power in football, Houllier added: "The power came with Bosman. But now it comes even one year before the end of a contract and the new FIFA rules.[LNB]"That is why the contract does not mean a lot. This is why at some stage we need to think about the future because you know teams that succeed have got a certain type of stability.[LNB]"What Chelsea are doing is interesting because they won the double but look at the team and how long they have played together.[LNB]"You see the team now and they are gradually improving and to get stability and to improve the level of your football, you need a bit more protection."
