Juan Martin del Potro will undergo another knee surgery on Monday, January 27, 2020 in an attempt to return to tennis.  Del Potro’s team is hoping that this surgery will relieve his pain that prevented him not only from playing tennis but also affected his daily life.

That’s rough for del Potro.  He has struggled with injuries for many years. He was not able play with Federer during his Latin American tour late last year as a result of knee pain.

Dominic Thiem has split with former world number one Thomas Muster after just two weeks.  Thiem will stick with his current coaching team consisting of Nicolas Massu and his dad Wolfgang.

Thiem said, “We ended our working relationship. It did not fit. Its easy like that. It is just about work. We get along well personally and we said in the beginning. If anything is not alright, we will tell each other”.

Speaking of Thiem’s decision, Muster said, “”He’s a fine guy and likes to learn a lot. But he has also got some shortcomings he has to work on if he wants to be at the top. He has improved a lot, but he has to catch up in the technical, physical and foremost in the mental area. To be honest I have seen myself in this role for the next two years. Why he has chosen differently – I know why, but I don’t want to say the details.
