What team are you and how much do you have to spend? If you are a top side with a lot of money I find Ramires is a beast but I have no idea if he would leave Chelsea and how much they would want for him.
Cheick Tioté. I bought him at the start of my Arsenal save but he was injured in a friendly so I haven't really seen that much of him in game, but he's got four stars so when he's fit again I'm hoping he'll be solid in midfield.
You can check out Simão Mate Junior. He plays for Shandong (China) at the start of the game and went to Ajax in my game for just £2.7M. Looks like a really solid player for a cheap price.
