According to the latest reports, the Premier League giants have now agreed on a deal with the Portuguese outfit for the highly talented midfielder.
A statement released by Porto confirms that Arsenal will be a fee of around £34.2 million for the 22-year-old attacking midfielder from Portugal.
Vieira had an impressive season with Porto last year, and he managed to rack up 6 goals and 14 assists. The highly talented attacking midfielder helped his side win the title last year, and he will be hoping to showcase his qualities in the Premier League now.
It is no secret that Arsenal need to add more quality and depth to their side if they want to qualify for the Champions League next season, and signing the 22-year-old could prove to be a wise decision in the long run.
The Portuguese midfielder is technically gifted, and he can play across multiple positions in the midfield.
Despite being an attacking midfielder, Vieira can operate as a central midfielder as well, and his arrival will add creativity, composure and flair in the middle of the park for Mikel Arteta.
The 22-year-old is yet to reach his peak, and he is likely to improve further with game time and experience.
There is no doubt that he has the potential to justify the £34.2 million outlay and develop into a future star.
Arteta has done well to nurture young talents like Emile Smith Rowe, Bukayo Saka, Kieran Tierney, Martin Odegaard and Gabriel Martinelli at Arsenal so far, and Vieira could follow in their footsteps and continue his development under the tutelage of the Spaniard.
