Manchester United boss Sir Alex Ferguson is calm over the prospect of not adding to his squad before the market shuts.

"If a new signing happens it happens," Ferguson told Key 103.

"The squad we had last season is good enough.

"Carlos Tevez will be back for the Portsmouth game next week. Anderson is due back from the Olympics by the time we play Liverpool and Chelsea and Wayne Rooney will be more effective for playing 90 minutes against Newcastle. If we have to go with what we have, we will do."
