The star of Bulgarian tennis Grigor Dimitrov now has a new coach and his name is Dante Bottini.
The news has been confirmed by the Association of Tennis Professionals (ATP), which added to the tennis player's profile the name of the Argentine as coach. Cooperation between the two was discussed in early December, but had not been officially announced. Dante Bottini replaces the German Christian Groh, with whom Dimitrov worked last year. The most serious successes of the new coach are linked to Japanese Kei Nishikori, who managed to climb to number 4 in the world rankings under his guidance.
