Viktor Gyokeres transfer clause explained amid Arsenal striker huntArsenal’s pursuit of Sporting CP striker Gyokeres could get a boost. A clause activating today requires Sporting to pay his agent 10% if they reject a €60m (£51.6m) bid. Arsenal are reportedly willing to meet this price. Sporting, however, insists on €80m (£68.7m) and could raise it to €100m (£86m) if the clause is triggered. Gyokeres is due back in training next week after international duty.
