Welsh international striker Craig Bellamy is a familiar opponent to the captain, who is pleased to now be on the same side as him.

"He's a good one to have on your side, and he has a character and determination that hopeful can give us a bit of a lift. You can get a player that arrives and tells people what he thinks of them, so maybe we'll get reactions and progress as a team because we have a bit more fire in the side."
And of midfielder Nigel de Jong, captured from Hamburg SV, Dunne added: "He took to training straight away, he seemed very confident, speaks English and knows Vinnie as well, so he looks like a good signing."
