It's the same reason the club would never had cashed in on Sako - the return from promotion is much, much more than any one-off cash sum we'd get from a sale.
I believe Afobe will be a Premier League player in 12 months time - let's just hope it's with us. No chance he'll leave before then, unless someone wants to bid stupid money for him.
I would be more worried about someone poaching Iorfa at this stage. Reviews yesterday all over the net, were all sprinkled with wonderlust.
With Iorfa worth upwards of £100m and Afobe around the £50m mark, together with Ismails £100m plus inflation, we are putting together a very valuable young squad.
