Celtic could be in for a tumultuous end to the transfer window with potential big moves on the horizon. Matt O’Riley is close to sealing a deal with Brighton & Hove Albion for a reported £26 million. Manchester City has shown interest in Kyogo Furuhashi and another young player as they look to bolster their forward line, although their plans are not set in stone.One player who could be worth revisiting for Celtic is Mathias Kvistgaarden, a striker from Brondby with a track record of impressive performances. Kvistgaarden has already caught the eye of Celtic in previous transfer windows, displaying a knack for finding the back of the net and making intelligent runs on the field. His speed and goal-scoring ability could be a valuable asset for Celtic if they need to strengthen their attack before the deadline.Kvistgaarden himself has expressed a desire to move to further his career and potentially earn a call-up to the Denmark national team. With talks also underway for Mateutz Bogusz from LAFC, Celtic should consider bringing Kvistgaarden on board for added quality in the final third before the window closes.
