Wayne Rooney worth his weight in gold to Manchester United, David Moyes says

David Moyes, the Manchester United manager, admitted it would have been impossible to replace talisman Wayne Rooney at Old Trafford.
Rooney celebrated signing a new five-and-a-half year contract by sealing United’s 2-0 Premier League win at Crystal Palace with a superb volleyed finish to double the advantage following Robin van Persie’s penalty.
Following the success at Selhurst Park which put United sixth in the table, Red Devils boss Moyes saluted the 28-year-old England striker and believes he will only get better after putting him in the bracket of the best players in world football.
Moyes said: “He’s a really important player and you think about the amount of clubs who wanted to sign him. He would have been too difficult to replace. There aren’t enough top players out there that you can get cheaply or easily.
“Wayne’s one of them, one of the top players. He shows it week in, week out for us and you can see the change in him – his leadership, what he’s trying to bring to the team.
“We want him to keep at it and I’m sure he will. He’s a boy who wants to continue to get better.”
