Europa League - Round-up: Portuguese shine
Porto won 1-0 at CSKA Moscow with a second-half goal from Colombian midfielder Fredy Guarin to continue a good night for Portugal in the Europa League following Braga's win over Liverpool.
CSKA, playing their 11th match in this season's competition, slumped to their first defeat after a superb effort from Porto's Guarin who turned his marker and scored from 25 metres.
Benfica made it a perfect night for Portuguese sides as they came from behind to beat Paris St Germain 2-1 thanks to an 81st minute winner by Franco Jara.
Gonzalo Castro equalised in the 72nd minute for Leverkusen only for Nilmar to break clear in the fourth minute of injury time to slot the winner.
Dutch side Twente have one boot in the quarter-finals after thrashing former UEFA Cup winners Zenit St Petersburg 3-0.
Luuk de Jong scored the opener after 25 minutes with Denny Landzaat making it two 11 minutes after the break.
And de Jong popped up to score again two minutes into stoppage time to all-but-guarantee that Twente will make the last eight.
Spartak Moscow also look odds-on to make the quarter-finals after beating Ajax 1-0 in Amsterdam thanks to a 57th-minute goal from Alex.
Four-times European champions Ajax wasted a host of chances, with Siem de Jong the main culprit, before Alex, another Brazilian, snatched an opportunist goal for Spartak in the 57th.
