Multiple reliable new sources are reporting that Al Hilal have submitted a concrete bid for Sehrou Guirassy. The forward remains under contract at Dortmund, but the opening offer has opened the door for discussions between the two clubs - though it is unclear at this stage whether the current bid will be enough to tempt them to part with a prized asset. Al Hilal remain optimistic, but the deal is not without hurdles. Barcelona continue to monitor developments and could yet re-enter the race if negotiations stall or valuation gaps remain unresolved. Al Hilal have been strong going forward this season, with 10 goals scored in 4 games (2.5 per game). Sehrou Guirassy would give them depth and keep that attacking firepower going all season. Dortmund continue to be linked with Axel Disasi, Tyrique George and Leandro Trossard while Al Hilal are also rumoured to be tracking Alexander Isak. More on this story as it develops.
