Galatasaray manager Okan Buruk knows there are weaknesses at Manchester United.
The Turkish giants are heading to Old Trafford in the Champions League group stages on Tuesday.
He spoke about the lack of preparation time for his team, but also suggested he may exploit United's left-back weakness.
"It is a very important match for both us and Manchester United," said Buruk to reporters.
"We played the match two days ago [a 2-1 win against Ankaragucu]. We don't have much training time. We trained in Istanbul and came back."
He added: "We worked out our plan for the match there. 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."
