Celtic's hopes for a strong finish in the Scottish Cup hinge on the return of midfielder Arne Engels, who is expected to provide a vital energy boost to the team. After a lackluster performance in their recent 1-0 victory over St Mirren, where the midfield appeared lethargic, Celtic manager Martin O’Neill is looking for solutions. Engels, who recently returned from a two-month injury layoff, could be the answer to the team's midfield woes. Former Celtic striker Chris Sutton highlighted that Engels possesses the athleticism and running power that the team is currently lacking. With the Scottish Cup semi-final against St Mirren approaching, the pressure is on for Engels to prove his worth as the club's record signing of £11 million. If selected, he could play a crucial role alongside Callum McGregor, who is also managing an injury, and Reo Hatate, who has struggled for form. The outcome of this match could determine Celtic's path to the final against Dunfermline Athletic on May 23.
