Enzo Maresca has given Robert Sanchez the chance to prove his quality, but he has failed to live up to the coach's expectations. The decision taken by Enzo Maresca is very reasonable and previously Hansi Flick had done the same thing to Inaki Pena, now he is more trusting the main goalkeeper position to Szczesny.
Chelsea certainly won't be short of players if Robert Sanchez chooses to leave the club, there are still plenty of other goalkeepers who can be relied on to strengthen the team.
Well, at least Chelsea still has quite a lot of other goalkeepers in their squad who will compete to be the best goalkeeper in the squad. And currently Chelsea has 4 goalkeepers, namely Robert Sanchez, Filip Jorgensen, Marcus Bettinelli and Lucas Bergstrom. And yes, in this case Enzo has many choices of goalkeepers that can be used, one of the goalkeepers has been considered not that good.
In fact, not only in the goalkeeper position, Chelsea also has many other reserve players in other positions. So the competition between players within this club can actually be very high. And Enzo usually makes wise decisions by rotating players in matches that are considered priority and those that are not. Like between the Premier League and the Conference League.
