Sunderland boss O'Neill delighted with victory over West Ham
O'Neill was more than satisfied with a victory which lifted his side six points clear of the relegation zone.
He said: "There's always pressure. The win was important for us. I think anybody in the bottom half of the table still has to be looking anxiously over their shoulder.
"But it was an important win for us - I think it's our fourth in seven games in the Premier League and in the context of things, it was good to win."
