He told whufc.com: "Many of the players are important. We have Scott Parker who is playing out of his skin, Matthew Upson, Robert Green, Valon Behrami all playing fantastically.
"It is the club's plan. The club want to get to a better level. In a few years' time they want to compete at high levels. The way the club choose to do this is to build a club of young, talented players and have experienced good players to lead them. That is why they don't want to sell the best players."
