Brentford defender has sent social media into overdrive after posing in full Celtic kit, sparking intense speculation about a permanent summer move to Glasgow.
​The 20-year-old English centre-back joined Brendan Rodgers’ side on a short-term loan in February 2026. He quickly established himself as a fan favourite, helping the Bhoys secure a stunning domestic league and cup double. While his loan contract officially concludes at the end of June, his latest Instagram post strongly suggests his heart remains at Parkhead.
​Fans React to the Kit Picture
​Arthur, who took home the Brentford U21 Player of the Year award last season, posted a series of training photos wearing Celtic’s distinctive green and white colours. For a player technically scheduled to return to his parent club in London, the visual statement was hard to ignore.
​Celtic supporters flooded the comments section within minutes of the upload. Many interpreted the post as a clear hint that negotiations for a permanent transfer are underway behind the scenes.
​Will Celtic Make a Permanent Move?
​The Scottish champions are eager to bolster their backline ahead of a demanding European campaign next season. Arthur’s physical presence and composure on the ball make him an ideal long-term asset.
​Brentford previously tied the highly rated defender down to a long-term contract running until 2031, meaning Thomas Frank’s side will likely demand a premium fee. However, if Arthur pushes for the move to continue his development in Scotland, Celtic could look to strike a landmark deal before the transfer window slams shut.
