Winners and losers: Luis Suarez is playing a different sport to everyone else

He's a funny player to watch, Luis Suarez. At times, he seems ungainly, clumsy even. Part if it is down to his gait: hunched, eyes fixed on the ball, tongue hanging out like a dog chasing a frisbee. But there's also something otherwordly about him, like he's actually, on some fundamental but nebulous level, playing some sport other than football out there, a street game whose rules are known only to him.

This, just to be clear, is a good thing. As far as playing style is concerned, football's global growth has come at the cost of idiosyncrasy; youngsters the world over now model themselves on the same handful of superstars wearing silver boots in slick TV adverts. Suarez, a unique footballer in the truest sense, has the air of a hold-out.

It is also palpably a good thing for Barcelona, for whom he serves as a rough, tough counterpoint to the more clean-cut stylings of Lionel Messi, Neymar et al. Suarez's value to the Blaugrana was plain to see on Wednesday night, when he put Paris Saint-Germain to the sword with two moments of individual brilliance at the Parc des Princes.

Both, brilliantly, involved nutmegs. Both left David Luiz with that old 7-1 look in his eyes. Both were celebrated with that feral scream and a kiss of his tattoos. Try all you might, but you cannot tame him.

Few gave Porto a snowball's chance in hell against Bayern Munich. Yes, Julen Lopetegui's side had been impressive in the second leg of their last-16 tie against Basel, but there was perhaps a touch of fortune about the whole thing: every shot Porto took seemed to nestle in the top corner of the net. But the Portuguese giants put down a real marker on Wednesday, rattling three goals past Bayern to give themselves a fighting chance of progressing to the last four.

In many ways, this was a case of Bayern being beaten at their own game: Porto pressed high up the pitch, forcing their opponents into errors. So arrived the first and second goals, with Xabi Alonso and Dante the guilty parties for the visitors.

The momentum appeared to have swung back Bayern's way when Thiago raced in to finish at the far post, but Jackson Martinez – recalled after an injury lay-off – put the icing on the cake just after the hour mark, dancing past the scrambling Manuel Neuer to finish calmly. More of the same and you wouldn't bet against them making things tricky for Pep Guardiola's men back in Bavaria.

The goalless draw between Atletico Madrid and city rivals Real failed to live up to recent meetings between the sides (notably last season's Champions League final and Atleti's revenge mission earlier this year) but the game will certainly live long in the memory of one man.

Atletico goalkeeper Jan Oblak turned in an impeccable display for Diego Simeone's side, repelling wave after wave of Real attacks. Whether it was plunging to his left to deny Gareth Bale or staying on his feet to make a reflex stop after Raphael Varane's gallop down the right flank, the 22-year-old proved a capable last line of defence for the hosts.

It has been some month for Oblak, who also played a major role in Atleti's penalty-shootout win over Bayer Leverkusen after coming off the bench. A few more displays like this and regular first-choice stopper Miguel Angel Moya might struggle to win his place back.

Robbed of Thiago Motta (injured), Zlatan Ibrahimovic and Marco Verratti (both suspended), Laurent Blanc must have known his side would be up against it when Barcelona came to town on Wednesday night. The PSG boss insisted before the game that his side could hurt the Catalans on the counter-attack but there was little of the cutting edge they displayed in their 3-2 victory over the same opponents in September.

Edinson Cavani has been something of a cup specialist this term (12 goals across Champions League, Coupe de France and Coupe de la Ligue; only eight in the league) but fluffed his lines when teed up by Ezequiel Lavezzi in the first half. Javier Pastore had an even better chance inside the first 10 minutes, but contrived to scuff well wide from six yards out.

That effort typified Pastore's performance. A player described this week as "the best player in the world" by Eric Cantona, the Argentine repeatedly ran down blind alleys and saw his passes cut off by Barcelona defenders. On his day, he is a player of rare poise and class, but here he looked listless. Not unlike a number of his team-mates in blue, it must be said.

Preferred to Brazilian youngster Wallace by coach Leonardo Jardim, the defender's age showed in the run-up to Juventus' winning goal on Tuesday. When a ball came over the top from Andrea Pirlo, Carvalho found himself on the wrong side of Alvaro Morata and, while trying to recover, sent the Spaniard tumbling.

It was the one error in what was otherwise a fine defensive performance from Les Monegasques, with Moroccan centre-back Aymen Abdennour especially impressive. Carvalho must hope that it doesn’t prove too costly when the sides reconvene at Stade Louis II next week.
