We need to rebuild this squad at some point soon and this is our last chance to sell Yaya. We either get £20m for him now, along with a huge amount of space on our wage bill to find a replacement, or we will lose him for nothing, or next to nothing in a year or two. It's just a matter of whether we think it's worth keeping him for his help on th field for a couple of years, knowing that we won't get any return from him in terms of helping us get a replacement at the end of that time. It's tough one, but I guess it really boils down to who we can get to replace him this summer, if we can't get a suitable replacement then we can't afford to let him go.
