Transfer Developments and Financial Details
Bayer Leverkusen are making significant advances towards bringing former player Moussa Diaby back to the Bundesliga while also aiming to bolster their defence with the acquisition of Facundo Medina from Marseille.
According to Sportingpedia sources, Diaby has agreed personal terms with Leverkusen but an agreement with current club Al-Ittihad is still pending. The transfer fee for Diaby is anticipated to remain below €30m.
On top of that, Bayer Leverkusen have struck agreements with both Medina and Marseille. The deal for the Argentina international is poised to cost an initial €23m, with the total package rising to €25m contingent on add-ons.

Moussa Diaby’s Prospective Comeback
Leverkusen’s pursuit of Diaby gained traction earlier this week. Despite interest from Benfica and Inter Milan, the Bundesliga side appears to have outmanoeuvred their competitors. Diaby previously joined Leverkusen from Paris Saint-Germain in 2019 for around €15m and developed into a key attacking threat, amassing 49 goals and 48 assists in 173 appearances in competitive fixtures.
A transfer below €30m would represent a significant coup for the German club, bringing Diaby back for less than half of the fee received just twelve months ago.
Facundo Medina’s Defensive Impact
The club identified Medina as a top left-sided defensive target, attracted by his ability to play as both a traditional full-back and the left central defender. Medina, under contract at Marseille until 2030, cost his current club approximately €20m following a permanent arrival from Lens after an initial loan spell last summer.
Having initially been considered a possible successor to Alejandro Grimaldo, Leverkusen subsequently brought in Miguel Gutiérrez from Napoli for a guaranteed €26m, with bonus clauses potentially pushing the figure to €30m. Medina’s addition would now provide manager Carles Martínez with two distinctly different options on the left side: the attack-minded Gutiérrez and the defensively robust, tactically flexible Medina.
Should both Diaby and Medina finalise their moves to the BayArena, Leverkusen will have committed nearly €55m in base transfer fees — an investment that bolsters both their attacking impetus and defensive stability ahead of the coming campaign.
