Abraham has been at Chelsea from an early age.
He has made it clear in interviews that his ambition was to play for Chelsea in the Premier League.
If he is going to realise that dream now is the time, he will never get a better opportunity than this year, he knows that & isn't going to give up his dream now it is in reach.
We have signed Wesley as Abraham's replacement, the 'mystery' striker will play a different style in my opinion.
