Craig Bellamy has warned his Great Britain teammates that Uruguay striker Luis Suarez is a special player that poses a real threat to their Olympic hopes.
Team GB only need a draw against the South Americans on Wednesday to qualify for the knockout stage.
Bellamy thinks that his side will need to be at the top of their game to stop a player like Suarez.
He said: "He is a really terrific player and the one thing I've seen over and over again is that he is able to create something out of absolutely nothing.
"You sometimes think he is going down a dead end but then he will show that spark of creativity that changes things completely.
"He will come up with a little flick or knock the ball through an opponent's legs and that's what makes him so dangerous."
Liverpool players Bellamy and Suarez will be on opposite sides at the Millennium Stadium for the crucial Group A clash.
