#3 Dani Parejo (Villareal) vs Thomas Partey (Arsenal)

With both Arsenal and Villareal boasting a plethora of attacking talents in their ranks, the game could be decided by which attack fares better. On current form, Dani Parejo has been in imperious form.
Since joining Villarreal last summer, he has quickly become their chief orchestrator, cutting opposition defences with incisive through-balls and controlling the tempo of games with elegant passes.
Thomas Partey will have the Herculean task of keeping Parejo quiet on the day. The Arsenal midfielder has been a mixed bag since arriving from the Spanish capital in October last year. He must ensure Parejo doesn't have too much time and space to work into, which would augur well for Arsenal's hopes of winning the game.
#4 Granit Xhaka (Arsenal) vs Samuel Chukwueze (Villareal)

Granit Xhaka has become more of a utility man for Arsenal and might start at left-back against Villareal, where he's likely come up against the marauding winger Samuel Chukwueze.
Tall, quick and with terrier-like pressing prowess, the Nigerian has looked unstoppable of late. He scored a sensational goal against Barcelona last week. And if that's a precursor of what's to come on Thursday, Xhaka could have a tough outing.
#5 Nicolas Pepe (Arsenal) vs Pervis Estupinan (Villareal)

While the jury is still out on Nicolas Pepe, he has been a key player for Arsenal in Europe this season, scoring five goals and chipping in with four assists.
His penchant of cutting onto his left foot is something to behold, and that's something Pervis Estupinan should be wary of. Estupinan will also have to track Nicolas Pepe's runs closely, as the Ivorian likes to cut inside and tee off other colleagues in advanced positions on the field.
