Pablo Carreno Busta - Gilles Muller Tennis prediction

Carreno Busta and Gilles Muller have played three times against each other, kind of expected that Muller won the match on hardcourt by 6-4 7-6 7-6 while Carreno Busta won both claycourt matches and in straight sets. Carreno is a different player than he was since their last match and really plays well on hardcourt.Still, Muller is one of the toughest players you get to play on hardcourts and I doubt that either of this two players will manage to win this one here in straight sets. I expect at least 4 sets in this match and for them to go over the line of games here.
