Barcelona 5-0 Leganes: 5 Hits and Flops | Copa del Rey 2019-20 

#3 Flop: Dimitrios Siovas

Siovas looked lost in defence and was duly exposed by a rampant Barca attack over the 90 minutes

There were poor defensive performances, but Siovas' display was particularly dreadful. Operating on the left-hand side of Leganes' three-man backline (3-4-2-1), the experienced Greece international struggled under pressure and looked lost as Barca were rampant.

Seconds before Griezmann's opener, you could see him step out of his defensive position and half-heartedly press Messi in possession. That movement proves key, as Messi embraces the pressure before unleashing a brilliant pass that splits three Leganes players and releases Semedo inside the box.

They - Siovas included - are left ball-watching as Griezmann takes a touch to set himself before firing through the helpless legs of Awaziem into the bottom corner. Lenglet's rather sheepish-looking celebration rather speaks volumes for how easy it was to double Barca's lead. Siovas was aware of his run across the six-yard box, didn't man-mark him tightly enough nor jump to try and challenge for possession as Messi's cross was drilled towards the near post. Instead he watches Lenglet head goalwards and looks bemused.

That's a theme for their next two goals: he's initially out of position as Frenkie de Jong feeds Messi, who gleefully drives into the box and shrugs off two half-hearted challenges before firing goalwards. It takes a big deflection off Tarin on the way through, sure, but if not for 's poor positioning, Messi doesn't have that opportunity to begin with.

For Arthur's goal, he's again caught ball-watching in the box as the attack continues down the opposite side to him. He reacts too slowly to stop the rebound, before his sliding block attempt proves futile as Messi effortlessly rounded Cuellar before slamming home for their fifth and final strike of a memorable evening.
