Paris Saint-Germain sporting director Leonardo has admitted that progressing into the Champions League quarter-finals will not be easy for his side.

The French outfit will take on Valencia in the last 16, the first leg of which will be played at the Mestalla on Tuesday.

"The squad as a whole is on top form," he told reporters. "Our players, even those who aren't getting much time on the pitch, deliver well.

"Valencia are also a team doing well; it won't be easy to advance. The four Spanish teams are in the running − this is not by chance."

PSG are currently six points clear at the top of Ligue 1.
