Rodgers says he won't change approach - but should he?

Celtic manager Brendan Rodgers insists he will not change his European approach despite suffering an embarrassing Champions League defeat at Borussia Dortmund.

The Germans repeatedly breached the Scottish champions' defence and ruthlessly punished their visitors, scoring five times in the first half alone.

The defeat is the third seven-goal loss the Celtic manager has endured in the competition after heavy losses to Barcelona and Paris St-Germain - no other coach has suffered more than one.

While Rodgers says his side "always have to adapt" against this calibre of opposition, he conceded that "sometimes the quality just breaks through that".

Speaking on TNT Sports, the 51-year-old added: "Will we camp in and just wait? No, we won't do that. We know it'll be difficult at times.

"Tonight, we just gave it away too easy and we got punished."

Celtic travelled to Dortmund on the back of a nine-game winning start to the season, with one of those victories a statement 5-1 win in their Champions League opener against Slovan Bratislava.

That run, which included 33 goals scored and just four conceded, fuelled optimism that the Glasgow side were finally about to take the next step in Europe.

But a humiliating night in Dortmund was a re-run of a horror movie Celtic fans have seen too many times before against elite level opposition.

"We went in high in confidence, we felt we were in a really good place," Rodgers said.

"We had to start much better as we gave away really cheap goals. And we got punished for loose bits of play and passes. They were ruthless in their finishing.

"It's very difficult for us to get to that level. It's a different level, with the greatest respect. We want to be more competitive.

"My job is to go away and inspire the players again. We need to learn from it or we will get punished at this level."

'It can't all be on Rodgers' - or can it?

Neil Lennon called on his former side to "stop the bleeding" amid the first-half demolition, but Celtic seem unable to prevent the floodgates from opening on occasions like this.

By the break, Rodgers' side had bled out, becoming the first British team to concede five goals in the first half of a major European game since Cwmbran Town against Progresul Bucharest in the 1997-98 Uefa Cup Winners' Cup.

A sobering stat for a sobering night, which Lennon said was all part of a learning process. Not long afterwards, Serhou Guirassy scored the German side's sixth goal.

Lennon was struggling to watch by the time Dortmund's seventh lasered past Kasper Schmeichel, but he was keen to stress that the defeat "can't all be on the manager".

In the aftermath, captain Callum McGregor also said Celtic "have to learn".

But over the course of the past eight years, there's been little sign of improvement or learning against this calibre of opponent.

Dortmund didn't need to target a particular attacking third to get at Celtic, highlighting their immense quality across the width of the pitch

With the Westfalenstadion clock ticking towards minute 82 and the scoreboard at 7-1, every Celtic player was in the Dortmund half as the ball turned over.

It resulted in the relentless home side racing clear with ease again, but only Schmeichel's boot prevented an eighth.

Actions like that give fuel to the criticism of naivety that will come Rodgers' way.

Across the Celtic manager's two spells, there’s been a 7-0 defeat at Barcelona, 5-0 at home to Paris St-Germain, plus another 7-1 in the away game in France and six shipped at Atletico Madrid last term.

The Celtic boss is the only coach to watch his team concede seven goals in a Champions League game more than once. Tuesday was the third occasion.

And with a trip to last season's Europa League winners Atalanta to come next, the Scottish champions risk being run ragged again against another high-octane side who thrive off their man-to-man approach.

"Atalanta will be a totally different test," former Scotland forward James McFadden said on Sportsound.

"They are so aggressive in their press, they will be relentless. Celtic will have to be so much better."

Ex-Celtic goalkeeper Pat Bonner added: "If you look at the way Celtic play in the league, they will try to win the ball high up the pitch. That mentality is in the players. It was proven tonight they can't do that against top teams.

"These teams can take four or five players out of the game with two or three passes, then they are getting at your back four.

"You have to come up with a different plan or structure to stay in the game."
