Daniel Kelly’s absence from Celtic’s preseason friendlies is indeed raising questions.

The young talent is noticeably missing from the lineup against Queens Park after missing the clash against Ayr, and there hasn’t been any official comment from Brendan Rodgers regarding an injury.
He hasn’t been away with Scotland over the summer.
This silence, coupled with the ongoing speculation about his future, suggests that negotiations over a new contract might be affecting his involvement. With his contract discussions stalled and interest from clubs across Europe, including Bayer Leverkusen, it’s possible that Celtic is being cautious about using him amidst the uncertainty.
Celtic’s decision to reject all approaches so far indicates they value him highly and would prefer to secure his future at the club. However, without a new contract in place and the January window allowing him to leave as a free agent, the situation remains precarious.
If Kelly and Celtic cannot agree on terms soon, his continued omission from matchday squads could become a more permanent situation, potentially paving the way for his exit.
