Aston Villa boss Martin O'Neill has defended his decision to sign only Tottenham outcast Wayne Routledge during the January transfer window.

O'Neill had entered the month intending to significantly strengthen the smallest squad in the Barclays Premier League and maintain Villa's strong push for a European spot.

O'Neill said: "This January, with the exception of Wayne, we haven't enjoyed the bonanza time we enjoyed 12 months ago when we brought in Ashley Young, John Carew and Shaun Maloney.

"We tried to also bring in Brad Guzan, an American goalkeeper with a lot of ability, only for the work permit application to be turned down.

"But January is a very difficult month, it is manic, a bit crazy. I made strong inquiries about several players I thought would strengthen the side but they were not available. It is as simple as that.

"In an ideal world, we would have liked to bring extra players in and, yes, I could have filled the squad with a number of people but I don't see the point of doing that just for the sake of it.

"We may have concerns over whether we get any injuries, but I have got great faith in the squad who have done brilliantly and we will go again now."
