Aston Villa have completed the signing of West Ham United defender James Collins.

Collins, who has penned a four-year contract, said: "I'm delighted to have it all sorted.

"It's a fantastic setting. I just can't wait to get cracking now.

"Aston Villa is a massive club so, after coming here looking around the place and I'm friendly with a few of the boys as well, it didn't take a lot of persuading on my part."

Collins added: "I loved my time at West Ham but I believe I have taken a step forward.

"I have come to Aston Villa to improve as a player and hopefully improve their team. I'll be looking to do that straight away."
