Former midfielder Roy Keane was critical of both Aaron Wan-Bissaka and Anthony Elanga following Manchester United's 4-1 defeat to Manchester City at the Etihad Stadium.
Goals either side of half-time from Kevin De Bruyne (2) and Riyad Mahrez (2) were enough to seal the bragging rights for City, despite Jadon Sancho netting an excellent equalsier for United midway through the first-half. De Bruyne scored either side of Sancho's strike to twice put City ahead.
City dominated the second-half and scored their third goal of the contest through a lovely finish from Mahrez. The former Leicester City man, via the aid of a deflection, fired home a volley after expertly connecting with De Bruyne's corner.
