The offer of Arsenal for Bayer Leverkusen Defender Piero Hincapie is worth around £ 45 million.
The Gunners have been incredibly busy this summer transfer window, as a result of which Viktor Gyokeres, Martin Zubimendi, Ebereechi Eze and Noni Madueke, among other things, end their waiting for the Premier League title.
Although most reinforcements of Mikel Arteta have been in attacking areas, the Spaniard wants to strengthen defensively before next week's deadline and Hincapie has been a name on Arsenal's Radar for months.
The Ecuador International has a release clause worth £ 52 million, but the Noord -Londers are investigating the possibility of concluding a deal with the new club of Erik ten Hag on reduced conditions.
Arsenal has submitted a bid worth £ 45 million for the center-back that they hope will be enough to secure its services.
It is understanding that every deal for hincapie will determine whether Porto can continue on Arsenal defender Jakub Kiwior.
Arteta's men travel to Liverpool for a top of the table conflict this Sunday after a huge promising start to their title challenge.
After a hard -fought victory at Old Trafford on the opening day of the season, Arsenal flew past Leeds in the Emirates last Saturday on a day where new signing Gyokeres opened his account for the club.
However, the journey to Anfield will not be the most difficult test of the Gunners and Arteta could be without skipper Martin Odegaard and Talesman Bukayo Saka for the collision.
The duo was both withdrawn during the victory against the whites beating, although the size of their injuries still has to be confirmed.
Ebereechi could nevertheless see their possible absence in from the start at Anfield after making his £ 68 million switch from Crystal Palace.
The International in England joined Arsenal after registering 14 goals and 11 assists last term for the Eagles on the way to FA Cup Glory.
