Meh.. Good riddance. I never liked Costa much and hated him when it was rumored that he was downing tools when Mourinho was still managing Chelsea. That kind of person has no honor and he doesn't deserve to play in the top clubs of Europe. It's better for him to sell out and do a big money move to China.
You make some good points there to be honest, he is a bit of an asshole. I don't know how he hasn't been sent off more times, always seems to get away with stuff.
Chelsea should cash in, you're right.
If Chelsea lose Costa they will get good money for him & replace him with a great striker. They are EPL Champions & now have CL football so they can attract a good replacement.
Chelsea have money so i think they would not get trouble to get Costa replacement if he really move this summer however the rumour says that Chelsea wants James Rodriguez and maybe the player are willing to move because in Real madrid James is not the main options for Zidane
football club in china league is ready to buy diego costa with much money big transfer
so if costa leave can buy striker with high quality, but if james rodgrigues replace costa is not equal, because james winger and costa striker
striker position in chelsea only diego costa is good quality, so if leave without buy striker high qualty can get many problem
