Responsibility

For the Premier League’s biggest clubs, this competition is usually an opportunity to blood youngsters and give fringe players valuable minutes.

However, only 35-year-old Danny Welbeck, who scored twice, emerged from the starters with a compelling case for more regular involvement.

Even Valentin Barco, despite scoring Chelsea‘s fifth goal, was partly at fault for Leeds‘ second and was among several players who repeatedly surrendered possession during a difficult first half.

Young attackers Estevao Willian and Jamie Gittens suffered the disappointment of being substituted at half-time, while £40m signing Geovany Quenda, who joined from Sporting, did not add to his solitary substitute appearance for the club as he watched from the bench.

Midfielder Reggie Watson, making his debut at the age of 16, was also withdrawn at the break after being booked.

Alonso later said he would not take a “cynical” view as some on the outside might about the difference in level between his proven stars and Chelsea‘s back-up options.

He added: “I know that probably I have to take the right decisions for them to show their best level, so it’s something that I will analyse and learn from today.”

Nevertheless, reaching the fourth round is important for Chelsea.

It is not only about preserving their hopes of silverware in a season without European football, but Chelsea are also a club that need as many competitive fixtures as possible.

They have a 27-man squad, supported by a strong academy pipeline, and these matches are vital for keeping a large group of players engaged throughout the campaign.

There is an irony, then, that Palmer, Rogers and Chelsea‘s other established stars may have secured future opportunities for the very fringe players whose performances had put the club’s EFL Cup campaign at risk.

The stats back up McInnes’ anger. Rangers had just over 46% possession during the 120 minutes in the Czech Republic, and just one shot on target.

They won fewer than 70% of their 16 tackles and committed 17 fouls.

“I can’t accept, and we shouldn’t accept, losing individual battles, duels, second balls, not winning enough tackles and just getting the momentum of the game going our way,” the former Hearts manager added.

“I thought we looked young, inexperienced at times. We’re trying to make some signings to help with that side of it but we need to do so much more as a team.

“We got what we deserved. If we’d won on penalties we would have taken it, of course, but it would only have covered over the cracks.

“I’m mortified with the performance. I know you can lose games of football but we should have enough in the building to take care of that tonight.”

Rangers had won their two previous games – a 5-1 win over St Mirren in the League Cup and the 1-0 victory against Jablonec at Ibrox – after drawing at Dundee United and losing at home to Hibernian in their opening two Premiership matches.

But McInnes feels this latest result may set them back.

“We went into this game scrambling for some sort of confidence, some positivity,” he said. “But I just thought the team that deserved to go through went through tonight and that’s hard for me to take.”

In the open air of the Raiffeisen Arena, with bedlam all around, there was nowhere to hide for Celtic or Martin O’Neill.

The Scottish champions had endured one of the darkest nights in their European history.

After going out to Kairat Almaty on penalties last year at this stage of the Champions League play-offs, that is saying something.

Four goals up on aggregate against LASK, O’Neill’s Celtic somehow conspired to implode in a second half with little sign of a response on the way to a 5-4 aggregate loss following extra time.

There was no hiding place, and the Celtic manager was frank when put in the spotlight at full-time.

“I’m responsible for this one,” he said.

“Without a doubt. Naturally it took me a long time to get over the Uefa Cup final in 2003 but this was majorly disappointing.

“In the context of things, one was a final which it would have been terrific to win, this was a qualifying game which we should have been able to get through.

“We know that we are a million miles from the finished article. That’s absolutely true. I think we thought that anyway.”
