Shinji Kagawa made a positive first impression at his unveiling as a Manchester United player last week, but the forward will be keen to replace words with action when he makes his debut for the Premier League giants.

Kagawa gave an assured performance in front of the cameras at Old Trafford, vowing to handle the pressure that comes with playing for one of the world's biggest clubs and acknowledging the need to adapt to a new league and culture.

But it is on the pitch where Kagawa will do his talking, and although the 23-year-old's arrival in Manchester has generated much excitement, there is also skepticism in some quarters which a strong start to his United career would help to alleviate.
