Tottenham striker Robbie Keane has talked up the threat of Manchester United forward Dimitar Berbatov as the Republic of Ireland prepare to face Bulgaria in their World Cup qualifier.
Keane said: "Of course, he is very dangerous. He is a fantastic player.
"I had the privilege to play with him for two years at Tottenham and he is a massive danger to us, so we have to be wary of him.
"They also have other players who are just as important to the Bulgarian team, but he is certainly a threat.
"He has got quality - he is good on the ball, he's great in the air, he can score a goal, so we will certainly have to be wary of him."
