Former Manchester United forward Michael Owen has aimed a swipe at Noussair Mazraoui for giving away a penalty in the Red Devils' humiliating 3-0 home defeat to Bournemouth.
Ruben Amorim's side were humbled by the Cherries on their own turf just seven days on from their dramatic late comeback in the Manchester Derby.
Andoni Iraola's side dominated proceedings at Old Trafford and took the lead through young defender Dean Huijsen who headed home unmarked from a free-kick.
Mazraoui the made an error in judgement to hand Bournemouth the chance to double their lead when he mistimed a challenge on Justin Kluivert in the penalty area less than 15 minutes after half-time.
