Emma Hayes admitted Chelsea played a boring game against Real Madrid as a 2-1 win at Stamford Bridge ensured progression to the Champions League quarter-finals with a game to spare.

In the first half, Chelsea struggled to find a way through against Real, already eliminated after collecting a single point from their four games.

Chances fell to Guro Reiten and Erin Cuthbert, both denied by goalkeeper Mylene Chavas, while Mia Fishel put an effort wide of the near post from close range.

It took a clumsy challenge from Real full-back Kenti Robles, bringing down the lively Niamh Charles as she darted into the box, to earn Chelsea the penalty from which Reiten finally broke the deadlock just past the hour.

Substitute Athenea tapped in to level as Real made Chelsea sweat on qualification, leaving them facing two dropped points and an awkward trip to play Paris FC next week needing a result to seal a last-eight berth.

But Cuthbert, wearing the armband with Millie Bright unlikely to be back this side of the international break, took charge and within a minute had forced the winning goal, her cross bouncing in off Chavas as the goalkeeper’s concentration deserted her.

“We expect to go through, that’s a bare minimum,” said Hayes. “We should expect to go through as group winners. That’s already a sign of progress, that we expect those things.

“I didn’t think it was a scintillating performance, I thought it was a boring game. Not every game is swashbuckling and dynamic. I thought it was flat.

“I think it was understandable. We had an amazing performance at the weekend against Manchester United. Our league is really tough and I think it showed in some of the flat play for us. But we controlled the game without maybe doing enough in the final third.

“I brought Lauren (James) on at half-time, I thought that helped. Got the penalty, concede a sloppy goal from back to front, a poor goal.

“Then a really good response to go 2-1 up, then managed the game somewhat to the end in what was an efficient performance, but it was boring.”

Hayes said she looked forward to rotating her side in what will now be a dead rubber in Paris next week.

“Managing a squad of players is tricky when you’re making multiple changes,” she said. “I didn’t want to change much from the weekend, I think you need to build rhythm.

“For us the priority has got to be experimenting, giving opportunities in one of these two games coming up; Brighton (in the Women’s Super League) and Paris.

“It’s making sure we get Millie Bright back, we get Nat Bjorn registered. Maybe there’s a new player coming at some point (reports say a club record deal has been agreed for Colombia international Mayra Ramirez).

“But we’ve got to get ourselves ready. If we want to progress, we’ve got to get better. I think it was comfortable and measured from us.”

Real boss Alberto Toril reflected on a game that got away from his side despite a spirited performance.

“We played with our strengths, we contained them,” he said. “We restricted them. They’re a great team and we’re happy with the performance, even though we’ve lost. Sometimes you learn from the defeats.”

Chelsea advanced to the quarter-finals of the Champions League with a game to spare after an own-goal from Real Madrid goalkeeper Mylene Chavas handed them a 2-1 win at Stamford Bridge.

Emma Hayes’ side looked to be facing the awkward prospect of requiring a result next week away at Paris FC when Real substitute Athenea del Castillo tapped in on the rebound, reacting quickest after goalkeeper Hannah Hampson had beaten out Hayley Raso’s effort with 20 minutes to play.

A penalty earlier in the second half from Guro Reiten had seemingly put Chelsea en route to the win they required.

But after the visitors had hit back it fell to Erin Cuthbert, wearing the armband with Millie Bright still absent, to lead by example, sending over a cross that bounced in off the unfortunate Real goalkeeper.

Chelsea’s first chance fell to the left foot of Cuthbert, drilled low against the legs of Chavas after Fran Kirby had found her with a deft through ball.

Jess Carter drilled a searching pass to the left flank that was helped on by Niamh Charles, rampaging forward from full-back, into the path of Reiten. She hit an audacious, dipping effort that was just clawed out from underneath the crossbar.

Real threatened through Colombia international Linda Caicedo, tricking her way in behind Kadeisha Buchanan and looking to poke it beyond Hampton from a devilish angle. The goalkeeper, making her Champions League debut, instinctively threw up a strong right hand and beat the ball away.

Reiten set up Cuthbert, who swung and missed her kick with the goal gaping, before the Scotland international and stand-in captain crossed to the near post to present Mia Fishel with seemingly an easy finish, but she could only guide it wide.

Hayes sent on Lauren James, fresh from her weekend hat-trick, at the break as her side searched for the goal that would seal a last-eight berth, whilst the precocious 18-year-old Caicedo, injured during the first half, was withdrawn by Real boss Alberto Toni.

Anything less than a win and qualification for Chelsea would go to the final matchday, a result likely needed away at impressive Champions League debutants Paris, twice conquerors of Real in this season’s competition.

The goal to radically alter that equation arrived just past the hour. Melanie Leupolz’s pass split Real’s defence and ran through to Cuthbert, arch-tormentor of her opposite number Kenti Robles.

The full-back’s challenge was a mess, scything Cuthbert to the ground. From the spot, Reiten put one Chelsea foot in the quarter-finals.

James looked to seal it with a goal all of her own making, cutting in from the right and standing up two defenders before racing beyond them and clipping a shot towards the near post that was brilliantly deflected away by Chavas.

Then all of a sudden, Chelsea switched off. There seemed little on for Real when the ball was pinged up to Raso, high up on the right of the box but with Charles in her path and only Athenea to aim for.

Instead she looked to do it herself, blasting low at goal, her shot beaten out by Hampson but into the path of the substitute who tapped home.

Fortune smiled on Hayes’ team almost at once, their lead restored within a minute when Chavas lost concentration at the critical moment and fumbled Cuthbert’s cross over her own line.
