McCallen hails treble TT winner Dunlop

Eleven-time Isle of Man TT winner Phillip McCallen praises Michael Dunlop after the Ballymoney rider's three victories from three races.

McCallen won four races at the TT in 1996 and Dunlop has the chance to surpass that feat this week.

McCallen tells BBC Sport's Richard Petrie that Dunlop's increased maturity, fitness and move to the Honda TT Legends team have led to his dominant performances.
