Martin O’Neill acknowledges that his efforts to secure his first January signing for Celtic have been hampered by his recent return as manager.

The 73-year-old has reassured fans that the club is making earnest attempts to bring in new players. However, he admitted that the brief amount of time since replacing the unsuccessful Wilfried Nancy has limited his ability to make swift and decisive moves.

Celtic has brought back centre-back Stephen Welsh from his loan at Motherwell, and Mexican defender Julian Araujo joined on loan from Bournemouth earlier in the month, ahead of the departures of Nancy and head of football operations, Paul Tisdale.

“We are really trying, honestly. As I mentioned, I don’t face any obstacles from the board,” O’Neill stated. His team currently holds third place in the Premiership and could overtake second-placed Rangers with a victory against Falkirk this evening.

“It’s great that everyone is eager to make some moves, and I’m not placing blame on anyone. We will make efforts to bring new players in,” he continued.

“But honestly, even though we’re halfway through January, it’s about assessing what will best suit us. We’ll have to see how things develop,” O’Neill concluded.

‘Again, it’s not perfect. We might end up having to do some things that, you take somebody on loan that you think you wouldn’t be looking to sign for three or four years, for instance, something like that.

‘I have an idea about a player and things are being presented to me. Now, of course, I would like to act more quickly. I think I’m trying to do that, and then I obviously have the other things to deal with, the clubs and then the players themselves. And some people that I would really like may choose to go elsewhere. If I, myself, had a bit more preparation for it, then I maybe could have worked a bit more quickly.’

O’Neill revealed that winger Jota, who picked up a serious knee injury against Dundee United last April, is likely to remain sidelined until the summer.

It was hoped the Portuguese attacker, in his second spell at the club, would be available for the final few months of the season, but O’Neill said: ‘In terms of the long-term injuries, I don’t see Jota being back this season.

‘I think that Alistair Johnston would probably make a fightback, and he’s hoping to be maybe some time in March, and that would be great if that’s the case. But the longer-term injuries, I don’t see it.’

Meanwhile, Kieran Tierney believes Celtic are finally beginning to heal now O’Neill is back at the helm after Nancy’s disastrous tenure.

The Frenchman lost six games out of eight including the Premier Sports Cup final to St Mirren at Hampden and the Old Firm game against Rangers at Celtic Park.

O’Neill, aided by assistant Shaun Maloney, won seven out of eight games in their first temporary spell in charge after Brendan Rodgers left the club in October and they recalibrated the Saturdya’s hammering of United.

Asked to sum up a chaotic period, Scotland defender Tierney said: ‘It was disappointing. It’s not good enough losing that many games in such a short space of time at Celtic, it is never acceptable.

‘For now, it is just about making it right and winning again. The first day we came back in and they (O’Neill and Maloney) were here, it was just like normal again.

‘We built up a good routine in the however many weeks they were there before, and we had good results, good momentum and it just feels like we’ve picked up from there.

‘I think at any club if you lose games, you’re going to lose confidence. But this group of staff that’s come in, they’re so good at giving you confidence and making you feel good about yourself. I think you could see that at the weekend as well.’
