Arsenal have agreed £22.5m deal for 25-year-old star

Arsenal have agreed to sanction the sale of defender Jakub Kiwior to Porto on loan with an obligation to buy for £22.5 million, according to The Sun.

The Gunners are determined to reinforce their backline with another centre-back, and they are discussing payment terms for Bayer Leverkusen defender Piero Hincapie.

The London giants are optimistic of finding an agreement with the former German champions. If a deal materialises, they are expected to part ways with Kiwior.

The 25-year-old has already agreed personal terms with Portuguese giants Porto and there is also an agreement on a loan deal with a £22.5m mandatory buy clause.

Alongside Kiwior, the likes of Reiss Nelson, Fabio Vieira, Albert Sambi Lokonga and Oleksandr Zinchenko are expected to leave before the deadline.

Vieira could be on his way to Stuttgart in the coming days. The German club have received a huge financial boost with the £70m sale of Nick Woltemade.

Woltemade is on his way to Newcastle United in a surprise transfer.
