Manchester United boss Sir Alex Ferguson has suggested that he could yet move for another player before the end of the transfer window.

United completed the signing of Robin van Persie on Friday, but Ferguson has indicated that his transfer business is not yet complete.

"I think that is maybe it [in terms of signings this summer]. Maybe in one other position," Ferguson told MUTV.

"We have spent a big amount of money and, if I need to go to the owners, I am sure they would say 'yes'. But it's only if a certain player would become available."

United face Everton in the Premier League on Monday.
