Quizzed on whether the Frenchman could figure in a Premier League clash with Sheffield United, Blues boss Mauricio Pochettino told reporters: “Yes, can be involved. That is very good news. To be involved tomorrow and be in the squad and to feel the competition after the pre-season is good news for us. We need to be calm and quiet so not to put all the pressure on him. Now he's going to evolve, know the Premier League. It's a big motivation for us, for the team-mates, and the fans to see a player that should be important for us and to be in the squad for the first time.”
