Chelsea boss Mauricio Pochettino is excited working with Raheem Sterling.
Sterling struggled in is first season at Chelsea.
Pochettino said: First of all we need to see us and see what is going on and why they are not performing in the way that we expect and then, of course, when all is clear, we cannot give excuses to them to not perform. We need to clear everything and say: 'come on, now it is up to you, show me you are ready to play for this football club'.
But it's true that the circumstances didn't help all these types of players that arrived from different clubs with different expectations.
"Some because they were so good and scored so many goals and performed really well and others because they were young or really talented. It's important to understand that we need to take the responsibility before we blame them."
