I can't comment upon DS as I don't know what was going on there, but TH is not going anywhere, nor does he want to! Think he'll do fine for us this season.
One swallow does not a summer make and all that, but Hemed was pony yesterday. The team that was fielded in the first half played with high tempo and incisive passing. A clinical striker probably would've had 3 goals in that half. Hemed was the weak link. I can't see him offering anything to the team in a 4-5-1 formation. £5m offered and it'd be a yes to selling him from me.
