Messi and Suárez to face off for first time in title decider

So we come to it: the biggest LaLiga game between Barcelona and Atlético Madrid for seven years. Forget the Champions League disappointments, the off-the-field murmurings about money problems and the lingering toxic cloud of the Super League, and get ready for a title showdown.

League leaders Atlético are two points clear of Real Madrid and Barca with four games to go. If the match produces a winner, that team will have the power to decide their own fate. A draw could be enough for Atleti. A defeat for either may prove fatal to their chances.

The last time these two teams met this late in the season with the title still on the line for both was on that famous final day in 2013-14, when Atleti went to Camp Nou knowing they would win the league if they did not lose the match. Alexis Sánchez broke the deadlock, Diego Godín equalised, and Atleti were crowned kings of Spain for the first time in 18 years.

Nothing will be decided this season on Saturday, of course, and as any LaLiga coach will tell the media at any given opportunity, "every game is a final". But this one feels a bit different. With Madrid and fourth-place Sevilla meeting this weekend, too, Barca and Atleti must sense this is a massive chance to get a hand on the trophy.

For the neutral, the fact we even have a title race in early May is something to celebrate. So dominant were Atleti in the first half of the season – 16 wins, two draws and one defeat from their first 19 games – that the rest were struggling to keep up.

In fact, according to Stats Perform AI, on January 22 Atleti had a 75.1 per cent chance of winning the title based on predicted results, while Barça's chances were just 12.4 per cent. As of April 30, however, that same predictor model gave Atleti a 38 per cent chance of winning the league, with Barca just behind on 32.6.

While Atleti have won only half of their past 16 league games, Barça have been one of Europe's most in-form sides in 2021, winning all but three of their 19 league matches since the turn of the year – and lifting the Copa del Rey. They have collected 49 points in 2021, the most in the division and eight more than the leaders.

History is also on their side in this fixture: the 1-0 defeat at the Wanda Metropolitano in the reverse game, when Yannick Carrasco grabbed a first-half winner, was their only league loss to Atleti in their most recent 21 meetings. They have not lost at home to them since Pepe Murcia's side ran out 3-1 winners in February 2006. Diego Simeone has drawn three and lost five of his league games in charge of Atleti at Camp Nou, making it his least favourite opposition ground as well as the scene of arguably his greatest coaching achievement.

This weekend's game is also the meeting of the best defence and attack in the division. Barça have scored 80 league goals, at least 19 more than anyone else, but Atleti have conceded a miserly 22. Attacks win games, defences win titles, as the adage goes.

Barca have actually faced the fewest shots (280) of any team in LaLiga this season, 40 fewer than Atleti, who are sixth best. However, the Blaugrana have conceded 33 goals from an Expected Goals Against figure of 37.0, whereas Atleti's 22 have come from an xGA of 33.7.

That highlights perhaps Atleti's greatest asset: based on Expected Goals on Target – an indicator of the quality of shots faced by a goalkeeper – Jan Oblak has prevented 7.1 goals this season, the highest figure in LaLiga. For teams in Europe's top-five leagues, no goalkeeper who has played more than 10 games this season has a better save percentage (79.1) than Atleti's Slovenian sensation.

Having missed the reverse fixture, this will be the first time Luis Suárez has faced Barca since his rather acrimonious departure at the end of last season. To date, the Uruguay striker – who has 166 career goals in LaLiga – has scored against all 30 of the teams he has faced in Spain's top flight.

Suárez has been a driving force of Atleti's title charge, even though he has only managed three goals in his most recent 11 games. With 19 goals in 28 league appearances overall in 2020-21, Suárez is averaging 0.79 per 90 minutes. Only one player has a better rate: Lionel Messi (0.92), the top scorer in the league with 28 and perhaps the most in-form player since the turn of the year.

Since January 1, Messi has scored 21 goals in 18 games, more than anyone else in Europe's top five leagues. Excluding one penalty scored, he has plundered 20 from an xG of just 11, giving him the biggest positive differential for anyone in those top five leagues in 2021. He is a man on a mission – perhaps his final mission for the club, if he doesn't agree to extend his contract.

Prevailing wisdom would suggest one of these former team-mates will decide this contest and, in turn, the fate of the title race. Barca and Atleti have waited seven years for a battle like this – who will hold their nerve?
