Newcastle boss Steve Bruce, speaking to Match of the Day: "In the first half we looked like we had played three games in six days. I felt we were flat and it was not really until we changed things at half-time and went higher up the pitch we caused them some problems. They stuck at it, they showed a bit of spirit.
"The introduction of 'Big Andy' [Carroll] had glimpses today of what he had 10 years ago. He looks well at the moment. Big Andy Carroll coming on was a huge help."
Southampton boss Ralph Hasenhuttl, speaking to Match of the Day: "I thought [defeat] was not deserved. It was our best away performance of the season. We had chances to be more than 1-0 up. It was a pity. Really frustrated for the guys.
"After we scored, I think we stopped a little bit playing. They had a big guy in front and only went for long balls. The first goal we didn't defend well and the second was a shot from outside the box. It is a pity, I didn't see a lot of chances for Newcastle today, plenty for us. We didn't get the result but it was a very good game from us."
