Interim Celtic boss Martin O'Neill insists new January signings are "absolutely essential" for the club. He hopes reinforcements arrive before their crucial Hearts clash on January 25, live on Sky Sports. The champions have only secured full-back Julian Araujo on loan from Bournemouth so far this month.

O'Neill ruled out new faces for the upcoming Scottish Cup tie or Europa League match with Bologna. However, he expressed optimism about additions for the key Scottish Premiership title race encounter at Tynecastle. Rivals Hearts and Rangers have already strengthened their squads, increasing pressure on Celtic's transfer activity.

When asked about links to West Ham striker Callum Wilson, O'Neill remained non-committal, stating he was unaware of the reports. He acknowledged the team's search for "elusive goalscorers" but emphasized that progress is being made on the transfer front ahead of the critical league fixture.
