England's two most decorated sides will clash in the Europa League after Liverpool and Manchester United were drawn against one another in the round of 16.
Liverpool will host the first leg at Anfield with Old Trafford staging the return after both sides came through their round-of-32 ties on Thursday night.
Jurgen Klopp's men defeated Augsburg 1-0 on aggregate while United overturned a first-leg deficit to beat FC Midtjylland 6-3 on aggregate.
Tottenham, the third Barclays Premier League club in the draw, have been handed a tough test as they face Klopp's former side Borussia Dortmund while Gary Neville's Valencia have an all-Spanish tie having been drawn against Athletic Bilbao.
Liverpool, five-time European Cup winners, have also tasted a trio of successes in the Europa League - lifting the then UEFA Cup in 1973, 1976 and 2001.
They come up against bitter rivals United who have three European Cup victories to their name but have never triumphed in this tournament.
Louis van Gaal's side slipped into the Europa League having failed to get out of their Champions League group stage and then went on to suffer a shock 2-1 defeat to FC Midtjylland in Demark.
But, with pressure mounting on the United boss, they turned the tie around as they recorded a 5-1 victory at Old Trafford - with young striker Marcus Rashford scoring a brace on his first-team debut.
Liverpool made heavy weather of their round of 32 tie with Augsburg, with a James Milner penalty early in Thursday's second leg the only goal across both games and they have also lost at home and away in the Premier League to United this season.
With both famous clubs struggling to get into the top four this season, winning the Europa League could yet prove to be the easiest way to qualify for next season's Champions League and that will no doubt add even more spice to an already mouth-watering affair.
Tottenham were impressive in their 3-0 win over Fiorentina as head coach Mauricio Pochettino continues to maintain his side will challenge for both the Europa League and Premier League - with Spurs currently second in the table.
Neville appears to have turned a corner at Valencia after struggling in his early time in charge at the Mestalla, and they face Primera Divison rivals Bilbao after a hefty 10-0 aggregate win over Rapid Vienna in the previous round.
Liverpool manager Jurgen Klopp says facing Manchester United in the last 16 of the Europa League was the "cool" tie he wanted.
Both are currently outside the Barclays Premier League's top four so Europa League success could be their best chance of returning to Europe's premier club competition next season.
Liverpool, who are preparing for the Capital One Cup final against Manchester City on Sunday, edged past German side Augsburg in the round of 32, with James Milner's early penalty at Anfield on Thursday the only goal across both legs.
The Reds have lost home and away to United in the league this season but Klopp insisted it was the draw he had been hoping for.
He said: "Obviously it is not easy. But you can ask my staff, when they asked me yesterday 'who do you want?' I said 'Manchester United'.
"It's great. We deserve these games, with the game yesterday. I think we have to clear something.
"We had a good game when I was here when we played against them, but we lost 1-0. It was not what we deserved on that day, but we got it.
"Life gives us the chance to make it better and that's what we have to do, and what we'll try.
"In this round, there were no easy games so we had no chance for an easy game. So we have Manchester United - cool."
