Karen Khachanov is showing great form in the European indoor tournaments with a high first serve percentage and a positive winners/unforced and forced errors differential. He is confidently progressing towards the final, displaying high quality in his game. On the other hand, Matteo Berrettini, with low quality in his previous match, may struggle against Khachanov. Therefore, it is likely that Karen will be able to overcome his opponent and claim victory in the tournament in Paris.
In the semifinal, Humbert will be able to take advantage of Khachanov's physical fatigue after a series of tough matches. The French tennis player will have the support of the crowd, which will give him energy. Humbert has a good serve and can find weaknesses in his tired opponent. It is likely that Karen will struggle with pressure and errors, while Humbert will be able to capitalize on his opportunities and win the match. My prediction is a victory for Ugo Humbert.
