Chelsea forward Raheem Sterling says he was left "fuming" and "raging" by his exit from Manchester City.
He started just 23 league games last season, and believes his sacrifices were not being rewarded.
"When you play your heart out, sacrifice some of your kids' birthdays, and then get treated in a certain way, it's disappointing.
"At the time I was fuming, raging, but it's gone, it's in the past and I can only focus on the present, which is now, here at Chelsea, and the opportunity I've got here to go out and showcase my talents once again.
