Andy Murray insists the revelation Andre Agassi took drugs during his career has not tarnished his opinion of his boyhood hero.

The former Wimbledon champion admitted in his autobiography he failed a test for crystal meth in 1997 and then lied about it to avoid a ban.

British number one Murray, who grew up idolising Agassi, revealed his surprise at the news but offered his support to the American, saying: "I guess it's something he has to deal with him himself. He's entitled to say whatever he wants and I wish him the best. I judge him as a tennis player; he was great, one of the best of all time. No one wants drugs in sport but everyone makes mistakes."
