Chelsea vs Manchester United: 3 battles to watch out for | Premier League 2019-20

3. Willian vs Aaron Wan-Bissaka

Aaron Wan-Bissaka has been decent for Manchester United so far

When Chelsea visited Old Trafford earlier this season, Manchester United summer signing Aaron Wan-Bissaka showcased an impressive all-around performance and helped the men in reds secure a clean-sheet in what was a thumping 4-0 victory for the home side.

Since Eden Hazard left the London club to join Real Madrid in the last summer transfer window, Chelsea veteran Willian Borges da Silva has given the opportunity to don the left-wing for the Blues with No. 10 on his back.

Even though the manager has shown his faith in Willian, his performances for the club have not been exceptional this term. As a result of what, he has racked up only 4 goals and 4 assists from 24 Premier League appearances.

Consequently, Lampard could drop Pedro - who has not performed convincingly well for Chelsea this season - and could field Willian - who could help Chelsea's youthful frontline with all his big-match experience.

Aaron Wan-Bissaka, on the other hand, has already made the club's right-back spot his own. Although some fans have started to consider him as one of the best full-backs in England's top division, there is still room for improvement in the attacking areas for Wan-Bisska.

If Willian finds success and rediscovers his lethal form against one of his favourite opponents, he could certainly give the English full-back a tough time on Monday night. Moreover, Chelsea will be in the hunt for their first victory over Manchester United in the 2019-20 season. We will have to wait and see whether Willian would be the man to give Chelsea a night to remember.
