Rafael caught the eye at right-back with some trademark marauding runs forward to support Antonio Valencia down the right wing. He stepped in when needed in defence and went close with a curling effort on goal midway through the second half.
Fellow defenders Rio Ferdinand and Jonny Evans have also been selected in our poll. Both made some vital last-ditch interceptions and were solid throughout the 90 minutes at the Emirates.
Phil Jones, who started in central midfield and finished at right-back following Rafael's substitution, produced yet another all-action display. He put his body on the line with some crucial blocks, particularly in the second half, and was unlucky not to open his account for the season after putting two good headed opportunities wide in the first period.
