Asmir Begovic has admitted that Bosnia-Herzegovina will be "aggressive" when dealing with Gareth Bale in their Euro 2016 qualifier.
The Real Madrid forward, who is Wales's top scorer in this qualifying campaign, has been struggling with a calf injury over the last month, but will start tomorrow's match in Zenica.
The Chelsea goalkeeper told reporters: "I know how good Bale is as I have played against him in England. We have to give everything. We need to be positive, play smart and act aggressively against Bale. It goes without saying.
"That it not to be malicious, but you have to be aggressive against a player like him. If you give him space to operate then he causes you all kinds of trouble. We have to by all costs try to avoid that. That's what I mean by aggressive.
"We're not a dirty team, but we have to play to our strengths and give him as little time as possible on the ball to work his magic."
Wales will qualify for next summer's tournament if they avoid defeat in Bosnia, while their hosts cannot qualify.
