Forward Marius Copil – Gilles Muller
The two players are currently in a good shape, with decent results in this season beginning, and in Sofia both have managed solid matches in previous tours.
The main weapon of the two players is a serve, with which they manage to create many gambling games on their own and the return is not the strength of any of them.
The prediction of this match is a first balanced set in which each of the two will approach the start of the match, focusing especially on winning their own services and waiting for the opponent to make a mistake.
