Celtic principal shareholder Dermot Desmond will meet this week with Martin O'Neill and Robbie Keane regarding the managerial vacancy. The club is open to O'Neill continuing as manager if terms are acceptable, though he could also take another advisory role. The 74-year-old delivered a dramatic domestic double in his two spells last season.

Robbie Keane is scheduled for formal talks with Celtic after resigning as Ferencvaros manager. The former Celtic striker, who won the Israeli Premier League and Hungarian title, is currently a free agent. Desmond is believed to be a huge admirer of the fellow Irishman, who Celtic sees as a strong candidate.

Celtic has also identified Craig Bellamy and Roberto Martinez as potential targets. Bellamy has reaffirmed his commitment to Wales, while Martinez's Portugal duties make him less likely. The club aims to appoint a manager before pre-season begins, creating urgency in their recruitment process.
