De Gea will be gone by next summer I think, it's the only thing that makes sense. Then you've got Henderson first choice keeper tied down for another 5 years still. 120k doesn't look too bad then.
One thing I really am looking forward to is some authority and communication between goalkeeper and backline, De Gea really lacks any kind of commanding presence in the box. Which for me makes a massive difference to your defence, been saying this for ages, De Gea doesn't give any confidence in the box at all, rarely claims anything.
