Unai Emery has been very active during this transfer window and could be set to continue Arsenal's spending with a move for Club Brugge's Brazilian attacker Wesley.
According to Belgian outlet HLN, the Gunners sent scouts to watch Wesley as his side took on Royal Excel Mouscron on Sunday, whilst scouts from Borussia Dortmund, Paris Saint-Germain and Monaco were also present.
Unfortunately for the player, he was sent off after just 11 minutes and will not have impressed the scouts.
However, it is believed the clubs remain interested in the 21-year-old, who emerged as an important player for his side as they won the Jupiler Pro League last season.
He made 44 appearances in all competitions for Club Brugge, scoring 13 times and creating a further two for his teammates. He was his side's third top scorer during the campaign as they comfortably finished top of the table.
Wesley is known for his physicality and speed, meaning he has all the tools to be successful in one of Europe's top leagues. He has carried his impressive form over into the new season for Club Brugge, scoring three times in as many games, despite seeing red after only 11 minutes during the most recent match.
Earlier this summer, Wesley was close to signing for Italian side Lazio, but Calciomercato reported that they club were forced to change their transfer targets following Felipe Anderson's departure to West Ham United.
With so much interest in Wesley, Arsenal may have a battle on their hands if they do choose to pursue a deal for the young Brazilian. He has clearly shown enough promise to draw interest from some of Europe's biggest clubs, and could be one to keep an eye on in the future.
