Boulaye Dia completes late Rennes move to boost attacking options

Published on: 02 September 2026

Stade Rennais have completed the signing of Boulaye Dia from Lazio, adding the experienced Senegal international to their squad in the final moments of the transfer window.

The 29-year-old forward has joined the Brittany club on loan, with an option for Rennes to make the move permanent. The deal gives Stade Rennais an immediate addition in attack as they prepare for a season that includes European football and high ambitions in Ligue 1.

According to L'Equipe, Rennes will pay €2m for the loan, while the purchase option has been set at €8m. The arrangement allows the club to strengthen its forward line without committing straight away to a permanent transfer, while retaining the opportunity to secure Dia’s services in the longer term.

Dia arrives after playing in both Spain and Italy, and his move to France represents a new challenge in Ligue 1. Rennes will expect him to adapt quickly and contribute to a team targeting a place among the leading sides in the French top flight.

His arrival also gives the club an experienced option at the top end of the pitch. Dia is the final recruit made by Stade Rennais during this transfer window, and there will be pressure on him to make an early impact as the team balances its domestic objectives with its Europa League campaign.

The Senegal international’s estimated market value is €5m, according to Transfermarkt. His annual salary in Italy was reported to be €2,560,000, equivalent to 1,664,000,000 CFA francs.

For Lazio, Dia’s departure comes shortly before their Serie A schedule continues. The Italian club are due to face Udinese in their third league match of the season.

Betting company 1xBet lists Lazio at odds of 2.55 to win that match, with a draw priced at 3.00 and an Udinese victory at 2.88. The source article also included a link inviting readers to download 1xBet.

Rennes’ decision to bring in Dia reflects their desire to add both experience and depth to an attack that will be required to compete on several fronts. The club have qualified for the Europa League and are also seeking a strong league campaign, making the Senegalese forward’s ability to settle quickly particularly important.

The loan structure gives both parties room to assess the move. Rennes can benefit from Dia’s experience immediately, while the €8m option provides a route to a permanent agreement if his performances meet the club’s expectations.
