Multiple sources have confirmed that Arsenal have officially submitted a bid for Jarell Quansah. The offer for the Leverkusen defender had been speculated for a number of weeks, but represents the first concrete bid for the player. While negotiations continue, they are said to be progressing. Arsenal remain optimistic, but the deal is not without hurdles. Chelsea, Real Madrid and Liverpool continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. Arsenal's back line has been a real strength this season, conceding just 0.8 goals per game (4 in 5). Jarell Quansah would be expected to slot into that unit and hold his own in an already solid setup. Speculation continues to connect Arsenal with Nicolas Paz Martinez, Joshua King and Breno while no fresh rumours surround Leverkusen. Want to see how the story develops?
