But thats not an excuse to seal up the deal for a striker - Gyokeres to be specific, of which £5 million has been what is keeping the move on pause. But what can we do, the board knows what they are doing, they maybe tight on budget or they are waiting to see if Sporting will have no option to accept the deal.
Seeing that Berta has seriously talked to multiple other targets
[e.g., Cristhian Mosquera and Eberechi Eze] makes me believe Arsenal isn't on a tight budget and IIRC, they didn't sign anyone in the previous January transfer window so there's plenty of money, but for some reason, they still want to save that £5M
[if I were them, I'd pay it right away to sign Gyökeres and then recoup portion of it through shirt sales].
