The 20-year-old joined Bayer Leverkusen from Hertha BSC in the summer of 2025 and quickly established himself as an important member of the squad. After recording five goals and six assists in 44 appearances during his first season, Maza has taken another step forward this campaign.
He has already contributed four goals and four assists in 14 appearances across all competitions, strengthening his reputation as one of the Bundesliga's most promising attacking midfielders.
His performances have attracted interest from several major clubs, including Arsenal, Manchester United, Manchester City, Atlético Madrid, Paris Saint-Germain, Tottenham, Chelsea and Aston Villa.
PSG have reportedly withdrawn from the pursuit, but Barcelona are now among the clubs monitoring his situation.
According to Bild, the Catalan club are following Maza's development, although there have been no concrete discussions with Leverkusen at this stage.
Leverkusen are keen to protect their investment and are close to agreeing a new contract with the Algeria international. His current deal runs until the summer of 2030, but the proposed extension would keep him at the BayArena until 2031.
Bild reports that the club have already submitted a written offer following several rounds of negotiations, with only details remaining before an agreement can be completed. Sky Germany has also reported that discussions are at an advanced stage.
The proposed contract is expected to reward Maza's progress with a significant salary increase. It is also understood that the new agreement will not contain a release clause, which would leave Leverkusen in a stronger position should clubs attempt to sign him in the future.
The extension is expected to be completed before Christmas, although the agreement has not yet been officially announced.
Maza has also become an established member of the Algeria national team, having made 25 senior appearances and scored three goals.
Leverkusen currently occupy fifth place in the Bundesliga after nine matches, with 16 points, and are also competing in the Europa League.
With his performances continuing to attract attention, the German club will be keen to complete the new agreement before the transfer interest develops into formal approaches.
