Celtic manager Brendan Rodgers called on his players to focus on the football and ease the dissent among fans with results after a 1-1 draw at Aberdeen exacerbated the concerns of the Hoops support.

Celtic ran out to chants of “sack the board” from the visiting fans and a banner reading “Celtic board, on your heads be it”.

Supporters were unhappy with a transfer window that saw Nicolas Kuhn and on-loan Norwich forward Adam Idah arrive and the likes of David Turnbull and Mikey Johnston depart.

Kuhn netted Celtic’s equaliser in the 63rd minute, four minutes after coming off the bench, but many supporters believe the failure to further strengthen the squad has risked their cinch Premiership title defence and they resumed their chants of dissent after the game.

The name “Lawwell” was central to the noise, after the influence of chairman Peter Lawwell and the record of his son, head of recruitment Mark Lawwell, came under scrutiny in recent days.

Rodgers had called for unity ahead of the game and he said afterwards: “I can only concentrate with the players on what we do on the field.

“You always find that winning games and performing well can ease those situations, and that’s what we aim to do.

“Supporters pay their money, they have every right to say what they want to say.

“For us it’s the field, we can only control that. If we can do that, then we will be okay.”

Rodgers, who felt his side lacked aggression in the second half, agreed it was “very important” not to let the complaints become a distraction to his players.

Although the fans were chanting against the board before and after the game, they applauded the players and manager after the final whistle and supported throughout.

“Whatever goes on outside of the field, you have to be able to deal with that,” he added.

“At a club like Celtic, and the biggest clubs, there will always be that pressure there. I don’t need to add any more pressure to the players. They understand, playing here.

“My job is to give them the confidence to find the results we need to find. But there’s still so many games and a long, long way to go.”

Aberdeen did not manage a single effort at goal in the first half but Bojan Miovski netted on the counter-attack in the 50th minute and the Dons had several opportunities to win the game in a strong second-half showing.

Caretaker manager Peter Leven revealed his simple message to his players at half-time: “Relax.”

He added: “Celtic are a good team, they are going to pin you back but when we turned possession over, we just needed to make a few more passes.

“We knew Celtic were going to press the first five seconds. I just said ‘believe in yourselves, be a bit more braver on the ball’. And I think you could see that in the second half.

“We had a few chances in the second half. The boys ran well second half, pressed them, passed the ball a lot better. It was just about belief.”

Aberdeen players were incensed that referee Steven McLean did not send off Maik Nawrocki after the defender fouled Miovski while already on a yellow card but Leven did not make much of the incident.

“I never saw it again,” the first-team coach said. “The second yellow card never happened but it’s one of these things the referee has got to deal with.”

Hibernian signed centre-back Nectar Triantis on loan from Sunderland as the winter transfer window entered its final evening.

The Australia Under-23 international was a regular under Hibs head coach Nick Montgomery during Central Coast Mariners’ A-League title-winning season before making three appearances for Sunderland this term.

Montgomery said: “We have been chasing Nectar for some time, and although we thought he’d remain at Sunderland, circumstances changed and we made a move to bring him to Hibs.”

Dundee, Livingston and St Johnstone have also made additions but more business is expected at Celtic and Rangers among others.

Celtic are set to wrap up the loan signing of Norwich and Republic of Ireland striker Adam Idah, who has scored seven goals this season, after the 22-year-old arrived in Glasgow on Wednesday.

Several players could be on their way out of Celtic Park with David Turnbull and Mikey Johnston tipped to join Cardiff and West Brom respectively, and James Forrest linked with an exit.

But Gustaf Lagerbielke’s proposed loan move to Italian side Lecce could be scuppered amid reports of further injury concerns over his fellow centre-back Cameron Carter-Vickers.

Rangers are expected to complete the signing of 20-year-old Colombian winger Oscar Cortes on loan from Lens with an option to buy after he arrived in Glasgow.

The Light Blues look to have been thwarted in their bid to land Brazilian left-back Jefte from Fluminense, with loan club APOEL Nicosia reportedly intent on keeping him until the end of the campaign.

However, uncertainty remains over the future of Gers left-back Ridvan Yilmaz, with Galatasaray said to be preparing an offer.

Reports from Italy also claimed Hellas Verona were set to launch a bid to sign striker Cyriel Dessers.

Dundee re-signed Norwich goalkeeper Jon McCracken on loan. McCracken’s return to Dens Park came following an initial loan deal being terminated in August after he lost his place to Trevor Carson.

The 23-year-old went on to join Accrington on an emergency loan and played 13 times and now cannot play for anyone else this season other than Dundee.

With Carson missing some games recently through injury, manager Tony Docherty told his club’s website: “It is important for me to have strong competition in every position for the last part of the season and I want that with our goalkeepers and bringing Jon in gives us a real level of competition.”

Livingston have signed midfielder David Carson on an 18-month deal after the 28-year-old made more than 160 appearances for Inverness.

Livi manager David Martindale, who is also hoping to sign a centre-back, said: “He can play in a number of positions but, for me, is best in a defensive midfield role. He has bags of endeavour and desire to work hard for the team and I’m sure this will see him quickly become a fans’ favourite.”

Kevin van Veen looks set to return to Scotland on a loan deal but it will not be at Motherwell. Assistant manager Stephen Frail gave fans fresh hope there might be a loan return for the Groningen striker on Thursday morning but it is understood only Kilmarnock and St Mirren are willing to meet the Dutch club’s wage demands.

Aberdeen are said to have failed in an effort to re-sign Mattie Pollock on loan from Watford a day after Barry Robson was sacked as manager, while Hearts are hoping to hold on to Lawrence Shankland after signing Scott Fraser on loan from Charlton on Wednesday.

St Johnstone announced the signing of striker Adama Sidibeh for an undisclosed fee from Northern Premier League club Warrington Rylands. The 25-year-old has signed until May 2026.

Ross County are hoping to add least one more player and possibly two.

Outside of the top flight, Queen’s Park head coach Callum Davidson believes he has pulled off “a bit of a coup” by signing 32-year-old former Liverpool, Rangers and Scotland defender Danny Wilson from Colorado Rapids.

Lowland League side Albion Rovers sold striker Joe Bevan to Premier League Burnley for an undisclosed fee. The 19-year-old scored 15 goals for Rovers, including nine in League Two, after joining from Camelon 12 months ago.
