It's taken Naby Keita a while to find his feet at Liverpool, but these were the kind of nights he was bought for. Here are three takeaways from the action. The all-Premier League tie between Manchester City and Tottenham Hotspur has a combined revenue of €1 billion. With a squad lacking reinforcements in the a year ago due to stadium building costs, they are third in the league, but only a point ahead of fifth-placed Chelsea.
But with pace, power and some work, he could be a beast in a better side.
It has been a season where he has struggled and there were doubts, but the Guinea global is now coming to the fore at just the right time.
There is much excitement about the potential of the Brazilian centre-back, who cost the Spanish giants €50 million.
In contrast to the first half, it was a rather dour second period, with little in the way of goalscoring opportunities created but that will suit Liverpool, who will be relieved not to have conceded an away goal. Porto will feel unlucky not to have scored.More news: This massive python just broke a record in the Florida Everglades
He wasn't terrible, but nor was he anywhere near as convincing, on the ball or off it, as Matip has been for most of the past few months.
"We gave a few too many set pieces away".
Guardiola has often been accused of overthinking his approach in big games, and the charge was leveled against him once more in north London on Tuesday, where Fabian Delph, Nicolas Otamendi and Riyad Mahrez all made the starting XI. Perhaps it would have been different had Aguero not had his early penalty saved, but the game was settled by Son, exploiting Fabian Delph's relative unfamiliarity with the left back role to slam a shot under Ederson with 12 minutes remaining after doing well to keep the ball in play after an initial heavy first touch.
"They dominated from the start and it could have been many more goals", Owen said on BT Sport. City haven't even reached a final, falling at this stage a year ago to Liverpool, but are the competition's top scorers this season with 26 goals. They were blitzed at Anfield in the first leg in 2018, losing 3-0, and were never able to recover.
City had little going for it all night, and Guardiola's lineup choices betrayed him nearly as much as his hesitancy to substitute early in the 1-0 loss to Spurs. Yes, they rode their luck at times here, but they were missing Andy Robertson (suspended) and Joel Matip (rested) who will return in the second-leg.
