Cape Town - Despite the deal being publicly backed by both the club's owner and manager, Petr Cech's move to Arsenal has left midfielder Nemanja Matic unhappy.
The Independent report that Nemanja Matic is concerned that Petr Cech recreates his success at new club, Arsenal.
Petr Cech ended his trophy-filled, 11-year stay at Chelsea by signing for Arsenal for a fee of £11 million but only after Chelsea owner Roman Abramovich allowed the Czech goalkeeper to move to a rival club.
Matic is the first player to express his unhappiness about the deal.
“Petr is a great guy and a great keeper." said Matic.
"It is going to be a very important signing for them. I am not happy because of that.
“We know that he is very professional. He is one of the best keepers. I hope this season he does not perform as he did here for 11 years.”
The 26-year-old Serbian midfielder shone for the Blues last season after creating a strong understanding with Cesc Fabregas in the middle of the park.
Matic rejoined Chelsea for a fee of £21 million in January 2014 after being allowed to leave in 2011 in a deal which brought David Luiz to the club from Benfica.
