Andy Murray has stoked the fire ahead of his second-round Wimbledon match after the British number one hit back at accusations of gamesmanship from opponent Ernests Gulbis.

The Latvian accused Murray of under-handed tactics the last time they met at Queen's last year, claiming the British number one feigned a thumb injury to disrupt the rhythm of the game.

Murray slipped over and landed awkwardly in a tense clash with Gulbis, which had reached 4-4 in the final set, prompting the Scot to call a medical time out.

The world number three recovered to prevail over Gulbis, but was forced to withdraw in the following round and Murray vehemently denied his opponent's claims of cheating.

"I've never done it, it's a form of cheating. It certainly does go on and some players do it to get an advantage but I'm one of the guys who doesn't do it," said Murray.

"After my thumb injury I couldn't grip the racquet the next day and I had to withdraw from the next round because of it so it's very disappointing to hear Gulbis' comments."

Gulbis, 20, shot to fame as a big-serving teenager but has been out of sorts this season and having lost at the first-round stage in seven of his past ten tournaments, he has seen his world ranking drift to 74.

But the Latvian is convinced he is now better prepared to handle Murray's mind games.

"Actually he didn't have anything wrong (last year)," he said. "He just broke my rhythm and I wasn't an experienced enough player to deal with it at the time."
