The Arsenal boss says United have been discreet but deadly in their performances.
Arsenal manager Arsene Wenger has admitted that he thinks rivals Manchester United have been an impressive unit whilst achieving their 20th league title.
Wenger believes it is far from the flashiest trophy success in the Ferguson era, but winning 27 out of 34 matches has to be admired.
The Gunners boss has also reiterated the club’s plan to hold a guard of honour for the Red Devils to celebrate their victory, despite the two teams having a deep rivalry for more than 15 years.
United will travel to the Emirates Stadium on Sunday as Arsenal aim to secure a Champions League place.
