Yellow Submarine look out of depth

Villarreal surpassed expectations to reach the semis after upsetting Juve and Bayern. Liverpool have all but shut the door with a 2-0 win at Anfield. Coach Unai Emery faces an improbable challenge against the Reds, who are chasing a quadruple of Champions League, Premier League, FA Cup and League Cup titles.

2 Only twice have a team lost the first leg of a European Cup semi-final 2-0 and gone through - Hamburg against Real Madrid in 1979-80 and Roma against Dundee United in 1983-84.

3 The Reds have never gone out after winning a first leg 2-0 at home in Europe. But they have conceded at least three goals in the away leg of each of their last three Champions League semi-finals.

1 Celtic are the only team to have completed a European quadruple in 1967. Man United, Barca, Inter, Bayern, Ajax and PSV have all won the treble of European Cup, league title and domestic cup.

10 Liverpool are on the verge of their 10th European Cup/Champions League final appearance, five higher than the next English side (Man United).

34 In the first leg, Thiago Alcantara gave a stunning performance from midfield, making 103 passes (with a 96.3% accuracy) and attempting 34 passes in the final third.

1 The Reds restricted Villarreal to just one shot on goal during the 90 minutes at Anfield. It’s hard to see the La Liga side overturning the two-goal deficit in the second leg.

20 Trent Alexander-Arnold won 100% of his ground duels in the first leg, made 20 entries into the final third and provided 15 crosses into the Villarreal box.
