Manchester United boss Sir Alex Ferguson has assured fans they're ready to compete with Manchester City and Chelsea in the transfer market.
Ferguson says there's no chance of United "sitting in an ivory tower" and letting other clubs dictate in the transfer market.
He told United Review: "Billionaire owners have introduced a new world that is turning football on its head.
"For our part, we cannot afford to sit in an ivory tower. We have to face the challenge.
"It is a healthy competition and it goes without saying that we will not shirk it and I don't think we are doing so.
"Although I let the transfer window shut without signing a new player, that is because we did our homework some time ago and didn't have to rush into any emergency buying.
"We had an interest in one player, and I thought we had a chance of bringing him in, but the other parties involved weren't ready and so we have put it away until the summer."
