#2 Liverpool 4-0 Barcelona (Aggregate 4-2, Semifinal)
After a humbling loss against Roma a year back, Barcelona lost a big first-leg advantage yet again. After a 3-0 win at home, it looked impossible for the Merseyside club to score four without conceding but they achieved the impossible. Divock Origi was handed the start in place of injured Roberto Firmino and he justified Klopp's trust by scoring a brace, may be the most important brace of his career.
Andrew Robertson's injury at the half-time proved to be a blessing in disguise. Wijnaldum came on to replace him as Milner switched to the left-back spot. The Dutch midfielder took Liverpool into the final with a scintillating display. He scored two goals inside two minutes and lifted the spirits of an already bouncing crowd at Anfield.
With 4-3 aggregate victory, Liverpool completed one of the best comebacks of Champions League history to reach the finals for the second year running.
#1 Ajax 2-3 Tottenham Hotspur (Aggregate 3-3, Semifinal)
After trailing 1-0 from the first leg, Tottenham Hotspur went on to concede two goals inside 35 minutes in Amsterdam. In no time, Pochettino's men found themselves chasing a three-goal deficit. To make into their first ever Champions League final, the North London outfit required a Harry Kane-less-attack to score three goals without conceding themselves in the second. Lucas Moura scored the first goal in the 55th minute but still, winning the tie only seemed a fantasy.
It was his second goal, after four minutes, which made the game a fascinating one. Everyone thought that they had witnessed the comebacks of all comebacks a day before at Anfield but the Brazilian, definitely, had some other plans. Mauricio Pochettino threw Erik Lamela into the mix in place of Keiran Trippier as Spurs tried to achieve the unthinkable.
In the 96th minute, Dele Alli flicked the ball down to the edge of the box where Lucas Moura was present. The former PSG man slotted a precise finish into the corner past Onana to complete his hat-trick and set up an exciting summit clash with Liverpool in Madrid.
