Arsene Wenger has backed David Moyes to be a success at Manchester United but insists he will need time to get a grip on the task at hand.
Moyes has had an indifferent start to his career as Manchester United manager and sees his Red Devils side languishing in an uncharacteristic eighth place in the Premier League.
Losses to Liverpool, Manchester City and West Brom have put Moyes under early pressure at Old Trafford and means the stakes for the game against Arsenal are higher than they have been in years.
Arsenal are currently top of the league five points clear of second place and eight ahead of United.
A win for the Gunners will be another step towards being considered genuine title contenders whereas a win for Manchester United will redeem Moyes' poor start.
The two teams have shared a great rivalry over the years but seeing Moyes in the dugout for the first time rings in a new era and Wenger has started the new rivalry peacefully by giving the Scotsman a vote of confidence.
Despite the poor start, Wenger believes Moyes can succeed at Old Trafford if given time and insists he has done exceptionally well in the opening months of his new job.
Speaking to reporters, Wenger said: "You need to give David Moyes time.
He has shown great competence at Everton, he needs time to get a grip of Manchester United, and you can see that in the results.
"When a guy [Sir Alex Ferguson] has been there for 26 years and goes, it takes time for the guy who comes in. It is dangerous and difficult for the guy who comes in. Moyes is handling the situation very well."
On this being the first time Wenger has faced United without Sir Alex Ferguson, Wenger said: "Our relationship will be more peaceful now, more serene. It will be new. In the last 17 years, it was the case that he was there and yes, it will be a bit strange, but this is still a very, very important game for us."
