Raheem Sterling opened the scoring for the visitors in the 17th minute, but Rodrigo Moreno's first goal for Leeds in the 59th minute, following an error from City keeper Ederson, gave his side a point they more than deserved.
Atletico Madrid had Luis Suarez in its side but was held to its second 0-0 draw in a week as the team failed to break down Villarreal with just two shots on target in the entire 90 minutes.

"It's been long ride definitely. Everything came to my mind when I had my whole family, people who I loved to help me through the tough, tough time," said Kvitova. "I was just playing in the Philippe Chatrier, it was such nice to win the match and to be in the quarterfinal."
Things changed though for Schalke in the 23rd minute when Suat Serdar was unable to continue after a tackle.

After both exchanged serves in the following two games, a more experienced Zhang then delivered a dominant performance in the tie-break to seal the first set.

Getafe went top of the table with that win and Jose Bordalas' men now visit Real Sociedad, whose defeat to Valencia served to confirm that they are missing the support of their home fans. The side from San Sebastian has won just one and lost four of the eight home matches since football returned to Spain in empty stadiums in the middle of June, and on Saturday it will be without the injured Adnan Januzaj.
