Paul Lambert admits talking to Sunderland boss Martin O'Neill before taking the Aston Villa job.

O'Neill quit Villa in mysterious circumstances two years ago.

But Lambert revealed: "I think he had a good time here, had a lot of success and had the place absolutely rocking, so if I need help I'll definitely give him a call. I don't have any problem making mistakes - I just need to learn from them.

"There are certain times when I'll need a bit of help and I'll phone him up and ask 'can you help'."
