PSG's Keylor Navas replaced with muscle problem

Pochettino replaced Keylor Navas with Sergio Rico at half-time in PSG's game with Strasbourg in a matchday 32 Ligue 1 clash. Some understood the decision, but others did not think it made sense despite there being an important Champions League match with Bayern in midweek.
However, 'Canal+' revealed that that was not the case and that it was due to muscle problems.
Mbappe had opened the scoring earlier in the game with one of his many quality moves. The Frenchman was not taken off until the 89th minute for Nagera despite the game being in the bag.
PSG will be hoping that Navas' injury is not too serious and that he will be available for Tuesday's Champions League quarter-final second leg.
