Manchester City are closing in on the Champions League latter stages - but at some cost.
The Citizens now have one foot in the Champions League quarter-finals due to their win on Tuesday night.
The Premier League giants, who won the competition last season, beat FC Copenhagen 3-1 away from home in their round of 16 first leg.
However, manager Pep Guardiola is now set to lose winger Jack Grealish for some time.
It's a pity, he's gutted," Guardiola told reporters.
I didn't speak with the doctor but it looks muscular. The last few days his mood at training was much better.
He played really good, he was helping us with the tempo. He wanted to continue but we didn't want to do even worse damage."
