Neil Lennon has offered his view on the pressure facing Martin O’Neill as Celtic prepare for a crucial league trip to Tynecastle on Sunday.

With O’Neill back in the dugout, attention has turned to whether reinforcements will arrive in time to influence the title race.

 

Celtic travel to face Hearts knowing the margins are tight. A win would cut the gap at the top to just three points and inject belief into O’Neill’s second spell. A defeat, however, would see that gap stretch to nine points and deepen pressure during a demanding run.

The January window remains open, yet Celtic activity has so far been limited. Supporter frustration has grown as rivals have moved quicker. That context makes Sunday’s match feel bigger than a normal league fixture.

Lennon, who knows both O’Neill and the demands of Celtic management, was clear about what the manager will be seeking. He spoke with certainty about the need for additions and the importance of backing the manager quickly. His comments reflect a wider belief that Celtic cannot stand still.

He said: (Premier Sports), “I think he needs players in, and I think he will push for that.

“I wouldn’t say demand it, but he has made it clear what he wants from the board.

“I’m sure the board will back him this week and get the players he wants in.

“They will be his players, not Paul Tisdale’s and not Wilfried Nancy’s, because that has had to change since Martin came in.

“Now he’s going to bring in players, whether that’s loans or signings, to get Celtic over the line for the season.”

The comments underline how much responsibility now sits with O’Neill. He returned to a squad that has been shaped by different ideas and short-term planning. That reality has made this window more important than most.

Celtic’s league position has removed any margin for error. Every fixture now carries weight, especially against direct rivals. Tynecastle is rarely forgiving when confidence is fragile.

O’Neill has already spoken about being closer to deals, though no signings have yet arrived. The balance between patience and urgency is delicate. Results will not wait for process to catch up.

The Hearts game sits in the middle of a demanding schedule. Celtic are also preparing for European action and a busy domestic run. Squad depth and freshness are becoming harder to manage.

If Celtic win on Sunday, the mood shifts quickly. Cutting the gap to three points would restore pressure at the top and validate O’Neill’s steady approach. It would also buy time for recruitment to follow.

A defeat would tell a different story. Falling nine points behind would leave little room for recovery and place immediate strain on the new regime. That is the reality Celtic face.

Lennon’s words suggest belief that the board will move. Whether those moves arrive before Sunday remains the key question. The answers may arrive very soon, both on and off the pitch.
