Liverpool probably expected to cruise into the fifth round of the FA Cup when they were drawn against Shrewsbury Town. After all, Jurgen Klopp's side are the current world champions and are running away with the Premier League. Meanwhile, Shrewsbury are battling it out in the bottom half League One.But the FA Cup showed its magic again on Sunday, with the Shrews coming back from two goals down to draw 2-2 with Liverpool and earn a replay at Anfield.Reds youngster Curtis Jones, who scored the winner against Everton in the third round, gave the visitors an early lead. 

It remained 1-0 until the break and the message from Shrewsbury manager Sam Ricketts at half-time would have been 'we're still in this, no silly mistakes!'

Unfortunately, Liverpool were gifted a second when Donald Love tapped the ball into his own net from close range in the 46th minute. 

Many, many teams would have probably given up there and then, but not Shrewsbury.  

Cue the comeback. 

The hosts were awarded a penalty just after the hour mark when Yasser Larouci brought down Josh Laurent.

Striker Jason Cummings - who had just come off the bench - made no mistake from the spot and rolled the ball past Adrian.  

Just 10 minutes later and Cummings struck again, running into the box before coolly slotting past the Liverpool goalkeeper again. 

The comeback was absolutely brilliant and even Mohamed Salah and Roberto Firmino coming off the bench wasn't enough for Klopp's side to find a late winner. 

Instead, they will have another game to add to their February fixture list. It will mean little to Liverpool, but an awful lot to Shrewsbury, who will now travel to Anfield for the replay. 

Man City, Chelsea, Arsenal, Man United and Tottenham have all lost to the Reds this season. But not Shrewsbury. 

The FA Cup really is magical.
