Zola has enjoyed a fine start to his career as a Premiership manager and despite a 3-1 home defeat to Bolton Wanderers he is happy pleased with the players.
Zola told the official site, "I am more than happy with the squad I have got and when I have the injured players back it will be too big for what we need.
"Right now, we don't need any more as we have lots of top players already and my task is to get the best out of them.
"I am happy with what I have got here and I want to get results with this squad. I am very pleased with my players and what they are giving me."
