William Gallas was sad, disappointed and yet defiantly ambitious following Arsenal's defeat at Tottenham on Tuesday night.

The result emphatically ended an unbeaten run stretching back just over eight years and was celebrated with gusto in the blue-and-white half of North London.

The Arsenal captain, who had been brought in to cover a quartet of absences at centre back, admitted this defeat was one his team would have to take squarely on the chin.

However he was at pains to stress that it must not affect their assault on the other trophies in their sights - starting against Newcastle in the FA Cup on Saturday.

"It is difficult to accept this defeat and 5-1 is too much," said Gallas. "All the players are very disappointed and sad. I think Tottenham were better than us and we have to accept that.

"During the warm-up I said to the players it would be difficult because they have not beaten us and I said we have to be careful.

"We started the game well but we then conceded the goal and then everything was not good for us.

"Sometimes it is difficult and it is not easy for some players to be calm. We were too nervous. We have to learn from that.

"Now we just have to be strong and forget everything because, on Saturday, we have another big game which will not be easy. Newcastle have a new manager and they want a result at the Emirates.

"We have to win that game because we have ambition. But [right now] the fans are upset and we are upset. All the Club are upset and we have to accept it."
