Nicolas Kuhn scored his first goal for Celtic but pre-match dissent from the visiting supporters at Pittodrie was amplified as a strong second-half performance from Aberdeen earned the hosts a point.

Celtic ran out to chants of “sack the board” and a banner which read “Celtic board, on your heads be it” as the fans expressed their displeasure over the club’s transfer window business.

Their team had a goal disallowed and hit the bar twice in a one-sided first half but Bojan Miovski gave Aberdeen the lead with their first effort at goal in the 50th minute and his 19th goal of the season.

German winger Kuhn levelled in the 64th minute in his second appearance for Celtic but the game remained in the balance and the 1-1 draw ended a run of six consecutive wins for the cinch Premiership leaders since they lost back-to-back games in December.

Aberdeen had first-team coach Peter Leven in charge following the sacking of manager Barry Robson and he handed a first start to the club’s sole January signing, on-loan Crystal Palace midfielder Killian Phillips.

Celtic had both of their new signings, German winger Kuhn and on-loan Norwich forward Adam Idah, on the bench as Maik Nawrocki replaced the injured Cameron Carter-Vickers.

The defender’s ball over the top earned Celtic their first real chance and Luis Palma was celebrating after converting the rebound from Liel Abada’s saved effort. The Honduran winger was clearly offside though, however it took the VAR team several minutes to disallow the goal.

Celtic continued to create a steady stream of first-half chances. Kelle Roos saved comfortably from Palma and Abada and the former missed a great opportunity after Alistair Johnston’s cross found him in space on the corner of the six-yard box. His shot hit the top of the bar and went over.

Paulo Bernardo lobbed a delicate effort over a crowded goalmouth and off the top of the bar as Celtic continued to dominate. They had 13 first-half shots at goal, but only three on target with Matt O’Riley and Alexandro Bernabei off target just before the break.

Aberdeen had barely managed to get the ball in the final third but they re-emerged from the interval with a new-found vigour and quickly turned defence into attack when a Celtic move up the left broke down.

Dante Polvara’s forward pass set Miovski up to run at Nawrocki and the striker shifted the ball inside before curling home from 18 yards.

The game was transformed. Aberdeen threatened from a series of set-pieces with Celtic blocking several shots and Phillips almost made himself an instant hero with an audacious 45-yard chip which had Joe Hart beaten but just drifted off target.

It was another recent signing that was soon celebrating though. Kuhn and Idah came on along with Anthony Ralston in the 59th minute and the winger soon made his mark as he cut in from the right, played a one-two and then got the ball back from Idah before shooting in off Nicky Devlin.

Both teams went all out to get ahead. O’Riley saw a deflected effort hit the outside of the post and Hart saved from Connor Barron after Nawrocki’s poor clearance.

The offside flag went up after good chances at either end and Graeme Shinnie looked all set to score only to hit Hart with his shot. Leighton Clarkson looked offside from Shinnie’s header before he got the ball back.

Miovski was definitely offside when he beat Hart to Clarkson’s low cross and knocked the ball into the net from close range.

Celtic finished strongly but Roos came off his line to foil O’Riley and substitute Stephen Welsh headed over with the last action of the game before the away supporters resumed chants against the board while applauding the players.

Aberdeen have confirmed the signing of Killian Phillips on loan until the end of the season.

The 21-year-old midfielder joins the Dons from Crystal Palace after spending the first half of the season on loan with Wycombe in Sky Bet League One.

After beginning his career with Drogheda United, Phillips moved to Palace in January 2022 and made his senior debut in the Carabao Cup before going on loan to Shrewsbury last season.

Speaking about the Republic of Ireland Under-21 international, Aberdeen boss Barry Robson said: “I’m pleased to bring Killian to the club as he’s a player we’ve admired for some time.

“He’s energetic, hardworking and his strength of character is matched by his technical ability.

“He’s proven this season already that he’s capable given the number of games he has amassed.

“He’s put in some big performances, including a man of the match display, scoring for Ireland Under-21s against Italy.

“He’s very good in both boxes and will add a real versatility to our midfield options.

“He has the right mentality to fit into our squad and we look forward to working with him in the second half of the season.”

Phillips could make his debut against Dundee in the cinch Premiership on Tuesday night.

Ruben Selles saluted the loyal Royals who stuck by his side after Reading ended a 378-day wait for an away league win with a 2-1 triumph at Wycombe.

Former Chairboy Lewis Wing scored the winning goal four minutes before half-time after Killian Phillips had cancelled out Sam Smith’s opener.

The under-fire boss believes his side were deserving of the three points and looked forward to brighter days after cutting the gap to League One safety.

“I know the fans have been suffering during the entire season for a lot of different reasons, one of them being us not being able to win as much away,” said Selles.

“I’m happy for them. They have always been supportive of the boys. It’s always a pleasure to have that amount of fans away from home, get a victory away from home and for the boys to celebrate together.

“We were the best team on the pitch for 100 minutes. The team is growing and I’m very proud of the players and how they played the game.”

The league’s bottom side fielded Nelson Abbey, 20, and Tyler Bindon, 18, at the heart of their defence, with full-back Andy Yiadom the only outfield player over the age of 30.

But they acquitted themselves well and saw out a victory which will have banished memories of their last away league fixture – a gut-wrenching late 3-2 defeat against Shrewsbury.

“We have a couple of young centre-backs growing with the games, getting experience with the league and we had a plan from the very beginning,” said Selles.

“We knew after the second goal, if we started to go lower and lower, we would get in trouble. But the team continued applying the pressure with the high-line.

“We were not defending for 50 minutes. It was a pleasure we could keep a good team like our opponent today away from our goal in the second half.”

Wycombe boss Matt Bloomfield was left to bemoan a growing injury list as his side’s winless league run stretched to six matches.

“It isn’t easy,” said Bloomfield. “We’ve got nine to 10 injuries and some big players are missing.

“It feels like we’re making at least one or two changes regularly due to injury, which is tough, but ultimately we have to be better than what we were.

“Competing for the second balls, running, heading, tackling, those little bits that go into a performance that are actually massive.

“I’ve said many times this season how proud I am of the performance but today wasn’t one of those days.

“We were poor and we have to make sure we’re ready to bounce back on Tuesday evening against Barnsley.”

Wycombe manager Matt Bloomfield expressed his relief after their 2-1 first-round FA Cup win at Bradford.

The Chairboys had been in control of the tie with a two-goal lead at half-time.

But the League Two side came back strongly after the break to make Wycombe battle hard for their win.

Bloomfield said: “We’re really pleased to be through because it was an uncomfortable afternoon, if I’m honest.

“I thought Bradford were fantastic in the work they did and the way they passed the ball. They created some good opportunities and I’ve got to be pleased with the way we defended our box.

“The amount of blocks we got in was fantastic. There’s loads to improve on in terms of our in-possession stuff but the majority of those boys have done five games in the last two weeks.

“I think it possibly showed. We looked a little bit leggy in the last half an hour so fair play to them for digging in and making sure we got the result.”

Killian Phillips, on loan from Crystal Palace, scored Wycombe’s opener before Sam Stubbs headed into his own net to extend the lead.

Bloomfield added: “KP had been due one because his performance levels have been really high recently. He’s been top for us with his energy, the way he gets us moving forward and the amount he puts into the game.”

Jamie Walker pulled one back for Bradford after 64 minutes as the home team piled on the pressure. Wycombe keeper Max Stryjek made saves from Walker, Andy Cook and Tyler Smith.

Bradford caretaker manager Mark Trueman said: “It was difficult because you’re going in at half-time 2-0 down thinking that we’ve not done a lot wrong.

“I felt the way we started the game was positive but obviously goals change games. We knew that we would always create chances and felt like we were always causing them a threat.

“We’re disappointed in the manner we’ve conceded the goals with individual errors. They happen with the threat that Wycombe have got.

“But I think we dominated for long periods in the second half and were a little bit unlucky not to get another goal.

“We knew if we scored quite early then it might give us a chance of forcing a draw at least. I’ve got to praise the players for their performance.

“They felt the second half was one of the better performances they’ve had all season. We’re disappointed but we can take a lot of positives from today.”

Bradford have been without a manager since Mark Hughes was sacked a month ago.

“The players have applied themselves in the right way,” added Trueman. “Yes, they could say they are a little unsettled but the performance levels didn’t really show that.”
