Galatasaray boss Okan Buruk has pointed to the left-back position as the weak link in the Manchester United team.
Currently, United have both Luke Shaw and Malacia out injured, while loanee Reguilon is also injured, leaving the team without a recognised left-back.
United boss Erik ten Hag has recently deployed both Diogo Dalot and Sofyan Amrabat in that position.
But Buruk has revealed his team will look to exploit the deficiency, and he also admits he does not know who Erik ten Hag will play.
Buruk said: “We have our thoughts based on the pros and cons of the opponent. Our opponent does not have an original left-back. We do not know what they will use there.
“It is our own game. We made a plan based on our team and our players. We will try to implement it on the field.”
