Wenger said: “They played well at Chelsea and were unlucky with the decisions. But when the players feel deeply that they have shown quality, they never give up.
“Victor Moses is a threat. They are solid at the back now with three centre backs and two protective midfielders. Overall I believe it is a team which is well balanced.
“Any team who fights not to go down finds some momentum. Every year they find it just before they are out of the league. They have found a structure of the team that is better suited for them maybe than before.”
