Of course, the Reds clinched the title in style on Monday via an emphatic 3-0 victory over Aston Villa at Old Trafford, prompting some to suggest the boss will select a rotated team against the Gunners and the remaining fixtures with Chelsea, Swansea and West Brom.
However, speaking during his weekly press conference at Carrington, Sir Alex insisted there will be no let-up from United and claimed his side should respect the clubs still fighting for league positions and, in particular, UEFA Champions League qualification.
“We have a few bumps and bruises from the other night but it is hopefully nothing serious and I expect to have a strong side on Sunday,” the boss told reporters.
“Having won the league, there's always a danger of falling into the trap of 'it's all over and we can relax' and enjoy ourselves but I think we've got a duty to other clubs who are chasing Champions League places.
“Also, the rivalry we've had with Arsenal and then Chelsea over the years does put an edge to these games anyway so hopefully we'll represent ourselves in the right way.”
