If we want him, we will have to get him next summer, he is in his last season at Ajax so next summer, he will leave.
If we get him, we would have to get rid of Trez, both of them on the field won't work well and benching one of them will give troubles.
So would you want to sell Trez if he keeps performing during the rest of the season as he is performing now and get Huntelaar who is unproven on the highest level or keep Trez?
I suggest we keep Trez and don't spent +/- 17-20MEuro on a player that might not make the difference.
