Roger Federer injury comeback under threat as star hit with 'mistakes' claim
Roger Federer has been warned of the "dangers" of making a return to the tour later this year following his third knee surgery. The 20-time Major winner has been out of action for almost a year and is set to make his comeback at the Laver Cup before playing the Swiss Indoors Basel, but he has been criticised for "making mistakes" in the past ahead of his return.
