However, things soon went quiet, with links to Sporting CP star Viktor Gyokeres resurfacing.
Arsenal will have to spend big on either player, with rumours of around £92.5million being required to entice Leipzig to sell Sesko, while Sporting CP president Federico Varandas stated last week: "Viktor Gyokeres won’t leave here for €60million (£51.2million) plus €10million (£8.5million) in add-ons. He won't, and the game the agent is playing will only make the situation worse. As of now, we haven't had one offer for him."
But Arsenal's pursuit of Sesko has taken a major step forward today with news emerging that Leipzig have already lined up their replacement.
