Atletico Madrid booked their place in the Copa del Rey quarter-finals with a comfortable 4-0 win over 10-man Elche.

They extended their winning streak to 15 games in the process, the longest such run in their history, with Alexander Sorloth the orchestrator as he guided Diego Simeone's men to a quick start.

The Norwegian opened the scoring in the eighth minute, netting Atletico's earliest goal in the Copa del Rey this season, as he struck a loose ball from close range.

He then extended their lead shortly before the half-hour mark. Bambo Diaby fouled Samuel Lino in the box, and Sorloth made no mistake from 12 yards, sending it past Miguel San Roman.

Elche were reduced to ten men just five minutes into the second half when Nico Mercau received a second booking, this one a tactical foul on Rodrigo Riquelme.

The Spaniard would then go on to score the first, hitting the back of the net with a brilliant long-range strike just 11 minutes later before Julian Alvarez, his replacement, wrapped up the win 15 minutes from time with a quick finish.

Data Debrief: Sorloth delivers for Simeone

In the build-up to this match, Simeone said he was hopeful that Sortloth could deliver even more, despite an impressive start to life at Atletico.

He has already netted eight goals in LaLiga, and he added another two to his tally in all competitions on Wednesday with calm finishing, as he netted with both of his shots, worth 1.01 expected goals (xG).

While this was Atletico's most comfortable victory in the competition this term, based on the scoreline, their 14 shots were actually the fewest they have attempted so far, though 11 of those were on target. By contrast, Elche only tested Juan Musso with four of their 10 efforts.
