Lionel Messi finally broke his goalscoring duck against Chelsea to give Barcelona the edge after the first leg of their Champions League last-16 tie.
Messi had failed to score in eight previous attempts against the Blues, but he was not to be denied on this occasion as he cancelled out Willian’s 62nd-minute opener.
A Chelsea clean sheet would have been a massive boost ahead of a daunting trip to the Camp Nou next month.
However, Messi’s equaliser 15 minutes from time means Antonio Conte’s men face an uphill battle to qualify for the quarter-finals of Europe’s showpiece competition.
Here are three talking points from Stamford Bridge…
Conte’s tactical approach so nearly pays dividends
But for the fatal error that led to Messi’s leveller, Chelsea would be heading to Catalonia in three weeks’ time with a one-goal lead to protect.
That they came so close to victory is testament to Conte’s tactical nous, which stifled Barcelona while also allowing the home side to flourish.
As expected, the visitors dominated the ball throughout the encounter. However, they created precious few opportunities as Chelsea’s back line held firm.
Conte had resisted the temptation to start with an out-and-out striker, with Alvaro Morata and Olivier Giroud both named on the bench.
The fluid movement of Pedro, Eden Hazard and Willian caused more problems than Barcelona have been used to this season and the Blues’ second-half goal was a deserved one.
Heading into the second leg, Conte will need to devise another masterplan if Chelsea are to proceed to the last eight.
Third time lucky for impressive Willian
The tricky Brazilian has by no means been a regular for Chelsea this season.
But he was given the nod against Barcelona in a three-man attack that featured Hazard as a false number nine.
It’s a system Conte has favoured recently, but although it failed to get the best out of Hazard, the same could not be said about Willian.
He was Chelsea’s chief threat and, on another night, could have walked off with the match ball.
Willian twice hit the post in the first-half, showing great skill on each occasion to create space and leave Barca keeper Marc-Andre ter Stegen with no chance.
Despite his misfortune, Willian was unbowed and he broke the deadlock with a pinpoint finish that raised the roof at Stamford Bridge.
It was a fitting reward for a top-class performance that highlighted his natural ability.
Surely he can’t be far away from cementing a regular spot in Conte’s starting XI?
Messi ends Chelsea goal drought to have decisive say
It is not often that British football fans get to see the little magician at such close quarters, so each time he arrives on these shores it is to be cherished.
Chelsea had a game-plan to nullify his influence and in the first half this worked superbly.
Although there were the usual sublime touches that we have come to expect, Messi was largely shackled by a solid rearguard display from Chelsea’s three-man central defence.
However, it only takes a side to switch off for a moment for the Argentinian to flex his muscles.
A misplaced pass from Andreas Christensen was intercepted by Andres Iniesta, whose pull back enabled Messi to slide the ball past Thibaut Courtois.
Once the ball had arrived to him in the box, there was no doubting where it would nestle.
Messi’s exuberant celebrations underlined the importance of his equaliser in the context of the tie.
It could be the decisive moment.
