Wenger called Arsenal's first defeat of the season, away to Middlesbrough on Monday, a mere blip and hit back at Grant, saying: "We focus on ourselves and our performances. We played a fantastic game against Aston Villa just two games ago. We had a very average game at Middlesbrough and we lost.
"My squad is very determined and very strong. If you had listened to what people said before the season we would be 10th or 12th in the league and be out of everything. At the moment we are in everything."
