When he gets it right Grønkjær can be almost unplayable and he is capable of carrying the ball from one box to the other.

The 26-year-old's career has been blighted through injury, but with his knee problems now a distant memory, he has been a regular in Chelsea's team for the past two seasons.

The winger will always be remembered for the worst possible international debut in 1999 when, after just 30 seconds, his poor back pass was converted by Italy's Filippo Inzaghi.

But Grønkjær will still be one to watch this summer.
