Celtic fans are speculating about a possible return of Matt O'Riley to the club following Brighton's defeat to Nottingham Forest. The Danish international was substituted in at half-time during a troubling 7-0 loss, which has fueled speculation due to his limited playing time at Brighton and the potential for a summer return. A supporter suggested that he could be brought back for £8/9m in the summer. O'Riley's positive relationship with Celtic manager Brendan Rodgers, whom he credited for his development, might significantly influence a move back to Parkhead.
