Arteta was full of praise for his side’s fighting spirit after they battled to a draw in the first leg of their Carabao Cup semi-final tie against Liverpool.
“We revel against the situation,” the Arsenal boss told Sky Sports. “The players showed great fight, determination, brotherhood. You saw the emotion, we never gave up. Credit to the boys.
“I don’t know if the red card inspired them but it took the fight. You need a certain attitude to play in these games and the boys did that. We played the game we had to play, which is not our game. I have not seen it back, they checked it so probably a red card.
“To plan with the numbers we have, we don’t have any midfielders, becomes really complicated, because whatever we do is not natural.
“The extra motivation to play a derby [at Tottenham on Sunday] brings the energy when you don’t have it. No excuses, we have to play it.”
