United are happy to take some pressure off their wage bill, hence the discount, he didn't fit into Amorim's scheme anyway so it's a win-win move. It will be interesting to see how he will do at Chelsea, he was once considered a very promising player. Chelsea are on the rise now and I wouldn't be surprised if this gives a good boost to his career. And yes, I think he improved his salary conditions, otherwise why would he sign such a long-term contract - 7 years is a lot.
