Celtic have completed the signing of Haissem Hassan from Oviedo on a four-year contract with an option for a fifth year. Sky Sports reported an initial fee of £6 million, rising to £9 million through performance-related add-ons, with some bonuses tied to Celtic reaching the Champions League league phase. The Daily Record has put the overall value at £10 million, but that figure is disputed.

Hassan's view of the move

Hassan has not sounded like a player unsure about the step. Speaking to goal.com, he said: "With Celtic's history, all the great players, the fans and the atmosphere, I think this is the perfect moment for me. I know I'm joining a big club, the biggest club in Scotland, and I'm really looking forward to taking the next step."

He also said: "At 24, I think it's a good moment for me to move away from Spain. I've been there for six years." That lines up with the timing of the move, even if no one should pretend the transfer fee alone explains it.

Hassan added that football should be enjoyable and that his first job is to bring enjoyment to fans who come to the stadium. That fits the profile Celtic usually want from an attacking signing, and it sits neatly beside the club's wider transfer activity.

Celtic are also pursuing N. Sigur, described as a 22-year-old with 22 caps for Canada who can play as a No.6, No.8 or right-back cover. Mika Baur is expected to join from SC Paderborn 07 for £6.8 million, after Celtic's earlier £4 million bid was rejected. The Daily Record also says the club can add two more players by Tuesday and are still looking for a left-back and another goalkeeper.

Celtic's wider transfer push

The timing matters because Celtic are not operating from a position of pressure in the league. They finished first in the Premiership, are on a five-game winning run, and ended the 2025 championship round with 82 points. Recruitment at that point is less about rescue and more about keeping the squad sharp while the market is still open.

Martin O'Neill said: "I think the club has done really well to secure a player of such quality, with a number of other clubs interested in him. He is someone who I think has the ability and experience to do very well for us, performing at a high level in domestic and international football. I know he is excited about being with us and I am sure our fans will enjoy the energy and attacking intent which Haissem will bring to matches. I hope he will become a very important member of our squad going forward."

That is the clearest read on this deal. Celtic have brought in an attacker they clearly rate, the fee structure gives the move upside without distorting the headline cost, and the club are still active elsewhere before the window tightens.
