It looks like Hemed might be sold according to Andy Naylor, because the Dwamena deal is going through.

I don't see it. Both Murray and Hemed scored more goals at Championship level, and Murray more at Prem level. Ulloa is better at holding the ball up, but that's about it. There is a reason he doesn't start at Leicester.
