M. Diaby has completed his return to Bayer Leverkusen on a five-year contract through to 2031, bringing him back to the club where he built his reputation in Germany. The winger returns after two seasons away, having left Leverkusen for Aston Villa in July 2023 and then moved to Al-Ittihad FC in July 2024. For Leverkusen, this is a reunion with a player who already delivered 49 goals and 47 assists in his first spell.

The move is straightforward transfer news, but it is also a clear statement from Leverkusen. They have gone back for a winger they already know can carry serious attacking output in the Bundesliga and across Europe.

What Leverkusen are getting back

Diaby's first spell at Leverkusen from 2019 to 2023 gave the club exactly the sort of production most wide players never reach. He finished that run with 49 goals and 47 assists in 172 appearances in all competitions, with 125 of those matches coming in the Bundesliga.

Those numbers explain why this return feels practical as much as emotional. Leverkusen are not gambling on a player who once looked promising. They are bringing back someone who was already central to their attack over a sustained period.

Simon Rolfes made that point in his comments to bundesliga.com. He said: "We've brought a great forward back to the Bundesliga in Moussa. He'll give our attacking game additional quality and more possibilities."

That is a fair read of the signing. Diaby's output in his first spell was not built on a short burst. Over 172 games, he gave Leverkusen goals, assists and a level of familiarity with the club that should lower the risk usually attached to a major attacking addition.

Diaby's view on the return

Diaby's own explanation for the move was rooted in his first years in Germany. Speaking to bundesliga.com, he said: "I came to Germany as a very young, inexperienced player. Leverkusen put a lot of trust in me and supported me. I haven't forgotten that and always remained in touch with Simon."

That quote gives the deal a bit more shape. This was not framed as a late-market opportunity with no history behind it. Diaby pointed to a relationship that had stayed alive even after he left for Aston Villa and then Saudi Arabia.

He will also wear the No.19 shirt again at the BayArena, another sign that Leverkusen are leaning into a return that is supposed to feel familiar on and off the pitch. In transfer terms, clubs often talk about profile fit. Leverkusen can point to a player who already knows the environment and has already produced elite end product there.

The immediate context at Leverkusen

The timing matters for Leverkusen's start to the new Bundesliga campaign. They are looking to bounce back from their opening 3-2 defeat at promoted Elversberg when they host Union Berlin on Saturday.

That does not mean Diaby's return guarantees an instant fix, and Leverkusen would be wise not to treat it that way. Still, the appeal of the move is obvious. A side trying to reset after an opening defeat has added a winger who previously gave them 96 direct goal contributions across his first spell.

Leverkusen's pitch to supporters is simple enough. Diaby knows the club, knows the league and has already shown he can decide games in this shirt.

Whether he starts immediately or needs a little time, the headline part is already settled: Diaby is back at Leverkusen on a contract running through to 2031, with Union Berlin due at the BayArena on Saturday.
