UEFA Champions League 2019-20: Borussia Dortmund vs FC Barcelona combined XI

Defensive midfielder: Axel Witsel (Borussia Dortmund)

Witsel provides an excellent protective cover to the back four

Axel Witsel was easily one of the signings of last season. He seamlessly slotted in at the heart of Dortmund's midfield and quickly turned into an instrumental figure in the squad.

The Belgian is both combative and industrious, whilst also an excellent passer of the ball. His penchant to break forward at will has also seen him register two assists in the league this term.

Attacking midfielder: Marco Reus (Borussia Dortmund)

With injury issues subsiding, Reus has hit the throttle again

Dortmund skipper Marco Reus is enjoying some of his best days with Der BVB, and has also started the new season on a fine note. He struck twice in the weekend's 4-0 demolition of Bayer Leverkusen, boosting his confidence ahead of the big game.

Reus has been on target against all the big sides he's faced with Dortmund over the years, and he now has a chance to add Barcelona to his ever-growing list of major scalps.

Right winger: Jadon Sancho (Borussia Dortmund)

One of the brightest young talents in the football circuit right now, Sancho's hot streak of assists show no signs of subsiding - he's got five of them already in the league this term. Quick, athletic, vigilant and insanely skilled, Sancho can be a huge menace to the Barcelona backline that has conceded seven times in four league games.

Left winger: Antoine Griezmann (Borussia Dortmund)

Griezmann will be gunning for his first Champions League goal with Barcelona

Tactically, Griezmann is likely going to partner Luis Suarez upfront for Barcelona in the actual game; he's only a left winger here to accommodate more players in this line-up.

The Frenchman is still adjusting to life at Barcelona; his brace against Real Betis is the only notable piece of action from the €120 million summer signing so far.

This is set to be his toughest outing yet with the Blaugrana, and Griezmann knows a thing or two about the opposition having lost 4-0 here just a year ago with Atletico Madrid.
