Zola: West Ham best place for Bellamy and Parker
"I know the players have had big offers but on the other hand we believe we are offering them the possibility to improve, to get better and better. Hopefully our players will see that and consider it," said Zola.
"The club is determined to keep the best players because we want to take the team to a better level.
"Sometimes you have to accept certain things - but at the moment we are determined to do this.
"We want to keep our players. We have targets to achieve and we know if we want to achieve them, then we have to keep our best players. We hope we can keep them."
