MANCHESTER, England, Jan 26 (Reuters) - Alex Ferguson called Arsene Wenger petty on Friday after the Arsenal manager questioned Manchester United's stamina in conceding two late goals in their 2-1 defeat in London last weekend.

Arsenal scored twice in the last 10 minutes at home on Sunday to snatch victory and keep United's lead in the Premier League to six points over Chelsea.

Ferguson admitted his side has shown a tendency to let in late goals on occasions this season but dismissed Wenger's theory, expressed by Arsenal midfielder Mathieu Flamini, that it was down to tiredness.

"In the game against Arsenal, (was it) a lack of concentration? 'Yes'," Ferguson told reporters on Friday.

"From a winning position we were all gutted. It was disappointing but in terms of the stamina side of it, it's absolute nonsense.

"I thought it was a bit petty, coming out with that nonsense. There's absolutely no evidence. In terms of endurance and that kind of thing, we are well in control of that."

Asked why Wenger might have made his remarks to his team, Ferguson said: "I'm not sure. I think it's maybe making him look great again. 'I'm the great Arsene Wenger'.
