Brendan Rodgers paid tribute to Celtic's "Champions League mentality" in their 6-0 rout of St. Johnstone at McDiarmid Park.

Kyogo Furuhashi scored twice, while Paulo Bernardo, Callum McGregor, Daizen Maeda and Adam Idah were also on target for the Hoops, who warmed up for their midweek European trip to Borussia Dortmund in emphatic fashion.

The dominant victory moved Celtic back to the top of the Scottish Premiership table - ahead of Aberdeen on goal difference - as they continued their perfect start to the season, with a sixth win in as many games.

And Rodgers was pleased by the character his players demonstrated.

"I thought this was an opportunity to show our mentality," he told Premier Sports. "All the noise has been about Dortmund, but I wanted a Champions League mentality here, and I thought the boys controlled the game.

"We wanted to keep our rhythm going. You see some of the guys coming in this evening, like Valle coming in at left-back, showing his composure.

"Most were looking at it as a tick-box before Dortmund, but for me, it was to show their mentality. Everyone will be flying on Tuesday night, but I want to see how they do when they’re here, or other grounds. It’s a case of just focusing in on that.

"I thought the variety of our game was very good; everything you'd want from your team."

Looking ahead to Tuesday's clash with Bundesliga giants Dortmund, he added: "[They] are a good team with top players, so we can't get away from that.

"OK, they've lost one or two [players] from last year, but I always say we make sure we press, make sure we attack. It's a tough game, but we'll look forward to it."

Celtic stormed to the top of the Scottish Premiership with a thumping 6-0 win away at St Johnstone.

The defending champions thought they had taken the lead early on through Daizen Maeda, but VAR intervened due to a foul in the build-up.

Nevertheless, a brace from Kyogo Furuhashi and Paulo Bernardo's sumptuous strike virtually ended the contest at half-time.

There was to be no mercy in the second half though, as captain Callum McGregor added a fourth for Celtic shortly after the restart.

Maeda and substitute Adam Idah added further gloss to the scoreline to make it six league wins out of six for Brendan Rodgers' side so far this campaign and take them top, ahead of Aberdeen on goal difference.

St Johnstone are now just a point above second bottom in the table.

Data Debrief: Defence first

Celtic have kept a clean sheet in each of their last six games in the league.

Their last longer run of games without conceding a goal in the competition was a run of seven games from 26 April 2015 to 9 August 2015, so as well as their rampant attack, Rodgers' team have a mean defence, with St Johnston accumulating only 0.29 expected goals (xG) on Saturday.

With two assists in this match, meanwhile, Nicolas Kuhn now has four in total for the season, which is two more than any other player in the Scottish Premiership.

Celtic manager Brendan Rodgers was delighted to see an “emotional” Reo Hatate back on the pitch before the Japan midfielder departs for the Asian Cup.

Hatate made his first appearance in 10 weeks when he came off the bench during Celtic’s 3-0 win over St Mirren.

The 26-year-old’s latest lay-off because of a hamstring injury was his third leg muscle injury of 2023 and he appeared to be in tears as Rodgers embraced him after the final whistle in Paisley.

Hatate will head off to Qatar with Japan and might not be back until February but Rodgers is excited to see the midfielder perform when he returns.

“You could see afterwards he was actually quite emotional to be back out on the pitch again,” the Celtic boss said. “He’s put in so much hard work and he’s a big, big player for us.

“So hopefully he can go away and get some minutes and keep his fitness up because when he comes back he’s going to be huge for us in the second half of the season.”

Paulo Bernardo is likely to remain a key player during Hatate’s absence after making major strides in recent weeks.

The 21-year-old Benfica loan midfielder provided two brilliant assists in Paisley to add to the goals he scored against Rangers and Dundee in the previous two games.

“It is all patience,” Rodgers said. “Sometimes at big clubs there is no patience with young players. You can see him growing and developing.

“When you have young players that is what tends to happen if their attitude is right and their mentality is right.

“He has come in in these last few games and created goals and scored goals and he has put his foot in too. He is tenacious. Absolutely delighted for him. It is now about consistency.

“He’s a great learner, he’s a different type of player, maybe not as dynamic as Hatate, but he’s functional and he learns.

“He knows the runs, he knows the pressing triggers, and he’s developing and improving.”

Celtic will see four players depart for Qatar with Daizen Maeda joining Hatate in the Japan squad and South Korea calling up Yang Hyun-jun and Oh Hyeon-gyu.

However, Kyogo Furuhashi will remain with Celtic after being overlooked by Japan.

“Daizen was originally in the squad and Reo got called up a bit later,” Rodgers said. “But Kyogo has been in and out of the squad so I was relaxed anyway. We had a look at all the numbers and what it might look like.

“But, obviously, if he stays it’s really good news for us. But, for him, I’m sure he would have wanted to play in it.”

Philippe Clement questioned the VAR process which ruled out a penalty claim in Rangers’ 2-1 defeat by Celtic at Parkhead.

Leading through a Paulo Bernardo goal in the first half, Celtic full-back Alistair Johnston appeared to handle the ball inside his own penalty area under pressure from Abdallah Sima.

The VAR check for handball came to nothing but it later emerged that Sima had been offside in the build-up.

Kyogo Furuhashi added a second just after the break before Rangers defender Leon Balogun was shown a straight red by referee Nick Walsh for denying Daizen Maeda a clear goalscoring opportunity.

Gers skipper James Tavernier curled in a wonderful free-kick in the 88th minute to make it an anxious ending for Celtic, who moved eight points clear of their Old Firm rivals at the top of the table having played two games more.

It was a first defeat for the Belgian in 17 games as Rangers boss and he was left perplexed.

“My biggest frustration isn’t Cyriel Dessers missing a chance because (Erling) Haaland and (Kylian) Mbappe miss chances like that,” said Clement, who claims he was handed a yellow card during the game “for reacting too hard on a ball that was clearly ours given to the other side”.

“My biggest frustration is that if there’s a clear handball, I don’t understand why it’s not a penalty given.

“It’s a clear thing so I’m curious about it.

“There was no communication towards me. And if the communication is that Sima is offside, I’m not a referee but there should have been a clear signal from VAR for offside.

“Then everyone knows the decision. There was no communication at that moment.

“Otherwise, the signal of the referee is not correct. So there’s been a mistake and it’s clear for everyone to see.

“I also make mistakes but it’s an expensive one today.”

Clement was not displeased with the way his side performed in a stadium which had home fans only amid an allocation dispute between the two clubs.

He said: “The match was a good promotion for Scottish football with two teams who wanted to win, attacked and created chances.

“I need to look at my side and I’m happy with what they showed me today.

“We had more shots than Celtic but we didn’t take our moments.

“They were more efficient on the day and when games are in the balance like that, you can lose them.

“It could have been a draw, we could have won it. But the circumstances weren’t on our side.

“My team reacted in the second half, even after a world-class goal to make it 2-0. It’s a very good goal and you can’t do too many things about it.

“But we never stopped, even with 10 men. We kept going and created enough chances to score our goal and others. We went until the end and everyone here became nervous.”

Celtic’s loan move for Benfica midfielder Paulo Bernardo was the highest-profile signing of a relatively quiet transfer deadline day in Scotland.

Celtic have an option to buy the 21-year-old, who follows Honduras winger Luis Palma and on-loan Liverpool defender Nat Phillips in arriving at Parkhead this week.

Midfielder Sead Haksabanovic joined Stoke from Celtic on a season-long loan, just days after expressing frustration over a lack of game time.

“I feel like a new experience and challenge will be good for me at this stage of my career,” the 24-year-old told Stoke’s website.

Ismaila Soro earlier left Celtic for Beitar Jerusalem – 19 months after his final appearance for the club – and another out-of-favour player, Albian Ajeti, was set to seal a move to Turkish football although there was no confirmation of his exit come the deadline.

Rangers manager Michael Beale lowered expectations of fans in the afternoon when he declared himself happy with his squad following nine summer signings.

A quiet evening ensued, although reports later claimed the club had rejected Stoke’s bid for centre-back Ben Davies.

“We don’t have any injuries so the squad is looking healthy, the squad size has come down in size and average age so we are good to go,” Beale said.

“Naturally every manager is going to sit here and say they would like one more but if we don’t then I am happy with the squad we have got moving forward.”

Aberdeen signed versatile 26-year-old right-sided Danish defender Stefan Gartenmann from Midtjylland on a season-long loan to make it 13 incoming transfers this summer. Out-of-favour defender Anthony Stewart rejoined MK Dons on a season-long loan.

Dundee had confirmed the first incoming signing of the cinch Premiership on deadline day by bringing in Burnley winger Marcel Lewis on loan until January. The 21-year-old was previously on Chelsea’s books and has played for Union St Gilloise and Accrington.

St Johnstone signed two players – 28-year-old Austrian midfielder Sven Sprangler following a trial period and 25-year-old Charlton winger Diallang Jaiyesimi on a season-long loan.

Motherwell signed 19-year-old left-back Georgie Gent from Blackburn on loan until the end of the season,

Kilmarnock left it late to seal a season-long loan deal for former Rangers youth striker Andy Dallas from Barnsley.

The 24-year-old only joined Barnsley from Solihull Moors in July and netted on
his debut for the Tykes. Dallas has scored more than 60 career goals with the likes of Stenhousemuir, Cambridge, Weymouth, Solihull and Chesterfield.

St Mirren manager Stephen Robinson warned that none of his players would be sold on the cheap after Aberdeen made an approach for Australia midfielder Keanu Baccus.

“There hasn’t been a formal bid, there have been conversations between the two clubs,” said Robinson, who had finished his business ahead of deadline day.

“We are not in a position where we were last year when we had to take offers for players that were below market value. We have steadied the ship and got our finances right.” .”

Ross County signed Scotland Under-21 international midfielder Scott High on loan from Huddersfield.

Manager Malky Mackay told County’s website: “I am delighted Scott has decided to join Ross County. At 22, he is a great age to join the club, and has experience playing in over 60 English Championship games.”

Chairman Roy MacGregor was no doubt delighted at a deal involving English Championship clubs as Ross Stewart’s move from Sunderland to Southampton earned County a seven-figure sell-on fee.

It was a quiet day in the east although Livingston  loaned defender Morgan Boyes to Inverness for the season and Hearts loaned Connor Smith to Scunthorpe and Harry Stone to Queen of the South.
