Richard Dunne says Ireland teammate Shay Given has made a big impact at Manchester City since his January arrival.
Dunne said: "He has done really well since he has come in. I don't think anyone has really been surprised - everyone knows how good he is.
"Obviously, he is a big loss for Newcastle - their fans and their players will know how good he was - and he has come in and just carried on.
"He is just doing the exact same things. Just the way he walks around and the confidence he gives off has been great for everyone."
