But Celtic manager Martin O’Neill was attracted to his “experience of high-level football”.

“He has also been involved in European competition, so we are bringing in a talented, experienced, international forward to really enhance our attacking options,” he told Celtic’s website.

Adamu is eyeing a league and Scottish Cup double while scoring “a lot of goals” and wants “to improve as a player”.

Asked what kind of player Celtic fans will see in action, he added: “I’m dangerous in the box and hungry for goals. That’s what the manager sees in me and I want to show that on the pitch.”

The announcement of 22-year-old Mvuka’s signing came eight minutes after the closure of the January transfer window.

However, the Norwegian is no stranger to the Scottish champions, having played against them in the Conference League in 2022 for Bodo/Glimt, where he was a team-mate of Celtic winger Sebastian Tounekti.

He joined Lorient in 2023 but has made only five starts and 10 substitute appearances for the side sitting ninth in Ligue 1.

“Joel is a talented player who has a very good level of experience achieved at some really good clubs,” O’Neill said.

“He will give the squad another option, he is very quick, able to play on both wings”

The 20-year-old Arthur has made just three appearances for Premier League outfit Brentford, including two starts in his season’s League Cup.

However, O’Neill thinks the England youth international is “an excellent player, with real attributes, good height, strength and speed”.

His arrival allows Stephen Welsh to return to Motherwell on loan after being recalled as cover during January.

Meanwhile, Kenny heads for the side sitting third in League One having failed to become a first pick since O’Neill’s return to Celtic.

The 22-year-old Irishman, signed in January 2024 from Shamrock Rovers, has played 22 times for Celtic this season, 12 of them starts, and scoring six times.

“It’s an exciting challenge. We know that the club is not at the place that it should be, but I’m here to help the team and to bring what I can to achieve our goal.”

Disasi has not played for more than a year for Chelsea and was placed in the club’s so‑called “bomb squad” after failing to secure a move last summer and deemed surplus to requirements by former head coach Enzo Maresca.

He later worked his way back into the under‑21s and first‑team training, although he did not make a senior appearance.

Disasi joined Chelsea from Monaco in 2023 in a £38m deal and spent the second half of last season on loan at Aston Villa.

But he is determined to prove his worth at West Ham as he added: “The club has given me the opportunity to show my quality on the pitch. I spoke with all the people here, and I feel that they really wanted me, so that’s why I’m here.

“Everyone knows my situation in the last few months, so I just want to get back on the field, feel the sensation of games and help the team.”

Aston Villa have agreed a deal to re-sign former midfielder Douglas Luiz on loan.

The 27-year-old is currently on loan at Nottingham Forest from Juventus, but is set to leave the City Ground before Monday’s transfer deadline and join Villa.

Chelsea were also interested in the Brazil international but sources told BBC Sport his preference was Villa, where he made 204 appearances between 2019 and 2024.

Villa sold Luiz to Juventus for £42.5m in June 2024 to help solve their profit and sustainability problems, but he made just three Serie A starts before joining Forest in August 2025.

Villa boss Unai Emery is looking to bolster his midfield options, with captain John McGinn out for up to two months with a knee issue and Boubacar Kamara expected to miss the rest of the season with a knee injury.

Emery’s side lost out on Conor Gallagher earlier this month after the England international opted to join Tottenham from Atletico Madrid for £35m.

Villa are third in the Premier League – four points behind leaders Arsenal – and have qualified for the Europa League last 16 with one league-phase game to spare.

Villa are also expected to complete the £18m signing of striker Tammy Abraham from Besiktas imminently after the striker had a medical in the UK.

The Turkish side activated an £11.2m option to buy loanee Abraham from Roma on Monday and are now set to sell the 28-year-old to Villa.
