Sir Alex Ferguson has paved the way for a resumption of his rivalry with Arsene Wenger after marking out Arsenal as the main challengers to Manchester United's Premier League crown.
United manager Ferguson admits he has been impressed by the way the north London club have started the campaign with an unbeaten run that has brought five victories from their opening six league games.
"They have started the season well," Ferguson said. "Their form has been very good and they have produced some very good performances. It's going to make it an interesting League."
