Vincent Kompany hailed Manchester City's work rate in difficult conditions as they swept aside Basel 4-0 in the Champions League, but knows his side can't let off in the second leg.
Kompany – playing his first game in the competition since injury curtailed his participation in the 2016 semi-final at Real Madrid – and centre-back partner Nicolas Otamendi endured some nervy moments early on in the last-16 tie against livewire forward Dimitri Oberlin.
But after Ilkay Gundogan converted Kevin De Bruyne's 14th-minute corner, the Premier League leaders shifted majestically through the gears, as Bernardo Silva and Sergio Aguero caught out Basel goalkeeper Tomas Vaclik with fine finishes.
