Chelsea manager Jose Mourinho was being honest about the state of his reserve players, saying that they are "unhappy and frustrated" due to lack of game time.

Having a squad filled with quality definitely has disadvantages, as the likes of Petr Cech, John Obi Mikel, Filipe Luis, and Andre Schurrle, who are, more or less, top-class talents, are being kept on the sidelines because of stiff competition. But Mourinho simply deals with them as they are.

"It's not a difficult situation for me," said the Portuguese.

"I'm very club, team, team, club, group. I think everybody has to be ready to sacrifice for the team, to give everything for the team, to think about the team, not to be selfish. This is the way I want a team to be."

He bared that professionalism is what he continually inculcates to his charges, which serves them well when they are called upon.

"Look at Mikel. The first time he played was Newcastle and he was our best player," he continued.

"How can he be our best player if he didn't play in three months? Because he was working every day at the top level. Sad, frustrated, not happy? Maybe. But professional. That's what I expect from the players."

"If they are not involved I don't have a secret to keeping them happy."

"They are unhappy and frustrated, and need to be patient, but the reality is that, to be successful and work at a high level, you don't need to be happy. All of them are professionals."

"The team is more important than individuals. Mark Schwarzer hasn't played a second, but if he has to play tomorrow he would because he's ready. He's trained very well. We may have a secret to make them work every day at a high level, but no secret to keep them happy."
