Celtic manager Martin O'Neill has confirmed midfielder Arne Engels did not want to play in recent matches amid his £22 million transfer to West Ham, leaving the club short of energy ahead of their Champions League qualifier against LASK. The Belgian's departure comes as Celtic prepare for a crucial European tie with a potential £40 million prize at stake.

Why did Engels refuse to play?

Engels, who joined Celtic last season, was reluctant to feature in recent games over fears an injury could jeopardize his move to West Ham. O'Neill admitted the situation was frustrating but understood the player's position. "He didn’t want to play in the matches in case he got injured," the manager said. "That was understandable, but for the football club, that’s a disappointment."

What does this mean for Celtic?

The midfielder's absence is a blow as Celtic look to replace his running power. With the transfer window closing, O'Neill must find a replacement quickly. The team, who finished third in the Premiership last season with 67 points (21W-4D-8L), will need to adapt without Engels as they chase a Champions League spot.

What’s next for Celtic?

Celtic face LASK in a high-stakes double-header, with the winners securing a potential £40 million windfall. O'Neill’s side will need to rely on their recent form-five straight wins, including a 3-1 victory over Heart of Midlothian on May 16-to overcome the challenge. The club remains three points behind league leaders Heart of Midlothian as they prepare for the new season.
