Champions League PIX: Liverpool down Porto; Spurs edge City

Images from the UEFA Champions League matches played on Tuesday

Goals from Naby Keita and Roberto Firmino earned Liverpool a 2-0 win over Porto on Tuesday to give Juergen Klopp's side the upper hand in their Champions League quarter-final tie.

Liverpool took a fifth-minute lead through a Keita shot which deflected off Porto midfielder Oliver Torres and beat the helpless Iker Casillas.

Firmino doubled the advantage in the 26th minute -- Jordan Henderson split the Porto defence with a superb pass to Trent Alexander-Arnold, whose low cross was tapped in from close range by the Brazilian.

Moussa Marega then had a low drive well saved by the legs of Liverpool keeper Alisson Becker and the Portuguese side did well to stay in the game in a scrappy second half to give themselves a chance of a comeback at home in next week's second leg.

Tottenham Hotspur forward Son Heung-min's late goal sealed a 1-0 home victory against Manchester City in an absorbing Champions League quarter-final first leg on Tuesday.

With Spurs talisman Harry Kane having hobbled off injured and favourites City beginning to turn the screw, Son sent the home fans inside the London club's majestic new stadium into delirium as he fired past Ederson in the 78th minute.

Quadruple-chasing City, beaten at the same stage last year by Liverpool, were not at their slick best and Sergio Aguero's first-half penalty miss proved costly.

The Argentine's spot kick was superbly saved by Hugo Lloris after VAR adjudged defender Danny Rose to have handled.

Tottenham showed great discipline to preserve their lead and will now go to The Etihad next Wednesday with their hopes of a first Champions League semi-final appearance intact
