As the ongoing transfer window continues to unveil the latest moves across England and the rest of Europe, Arsenal are close to signing Fabio Vieira after agreeing a stunning transfer for the Porto star.
The 22-year-old Viera is heading to London for a medical on Friday after Arsenal struck terms on a fee with the Portuguese champions.
The versatile attacking midfielder has a release clause of £42million.
However, Porto have accepted an initial offer of £30m plus add-ons worth up to £4m.
With this, Vieira looks to pen a five-year Arsenal contract after super agent Jorge Mendes took control of negotiations.
Vieira has spent his entire career at Porto, scoring 10 goals in 75 outings.
