The former Manchester City trainee has been outstanding for the Clarets this season.
"Tyrone has been outstanding for me since day one," he said. "For me he was a bargain at just £400,000.
"Normally you don't get ready made players, in the Premier League you have to go and spend six or seven million.
"But Tyrone Mears looks like he's been playing Premier League football for all his years.
"He has to keep playing like this week in week out because when you set a standard you don't want to fall below it. At the moment he is playing very well."
