Aston Villa boss Martin O'Neill admits he will be active in the January market.

O'Neill made two of his most astute signings during the January 2007 transfer window in John Carew and winger Ashley Young but knows attempts to sign players in mid-season can be frustrating.

He said: "I think that we should look now to try and strengthen if we could do in January.

"I know we get linked with all sorts of players but up front we've got Gabriel Agbonlahor, Carew, Marlon Harewood and young Nathan Delfouneso whom I'm hoping will come through eventually.

"But, from that viewpoint, you would be looking to try and strengthen in case anything happens to anyone.

"It can be easier said than done and business in January time can be frustrating although it worked out well two years ago (with Carew and Young)."
