Manchester United travel to Stamford Bridge in the Premier League on Saturday afternoon, desperately searching for a positive result, with Michael Carrick's side in danger of continuing one of their worst runs of form in decades.
The Red Devils were thrashed 3-0 by AFC Bournemouth last time out, which followed a humiliating 4-1 defeat to Como in the Champions League, leaving them winless in eight matches across all competitions.
Chelsea are hardly flying themselves, having lost 2-0 at home to Tottenham Hotspur before exiting the EFL Cup against Liverpool in midweek, but they will fancy their chances of exploiting United's defensive weaknesses.
The Opta supercomputer has backed the Blues to win 51.8% of its pre-match simulations, and Morgan Rogers could be central to their hopes of securing three points.
With Joao Pedro sidelined through injury, Xabi Alonso will need his other attacking players to step up, and the England star has already registered five goals and four assists in 11 appearances across all competitions this season.
However, Rogers could face a stern examination from Leny Yoro, who has been deployed at right-back amid United's injury problems.
Here, Football Whispers takes a look at the key battle between the two.
Morgan Rogers vs Leny Yoro – who will win this Chelsea vs Man Utd key battle?
Rogers and Yoro have contrasting strengths, but the available statistics suggest the Chelsea attacker could have the tools to cause the young defender plenty of problems.
Rogers has registered four Premier League goals and one assist, alongside 20 shots and 13 successful dribbles. He has also attempted 23 dribbles in total, demonstrating his willingness to take on defenders and create opportunities through individual skill.
Those numbers could spell trouble for Yoro, who has struggled on the ball, having recorded just two dribble attempts and one successful dribble across his 261 Premier League minutes this season.
The young Red Devils defender has, however, shown some small glimpses of promising defensive qualities, making eight tackles, recording 14 clearances and winning 13 of his 28 duels.
His ten interceptions also highlight his ability to read the game, potentially allowing him to cut out passes before Rogers can turn and drive at the defence.
However, Yoro has also made an error leading to a goal this season, and facing an attacker with Rogers' confidence could prove a particularly difficult assignment.
The Chelsea forward has won 48 of his 105 duels, while also drawing 12 fouls, suggesting he is capable of forcing defenders into difficult situations even when they manage to halt his progress.
Although Yoro's defensive numbers indicate that he can compete physically, Rogers' superior attacking output and ability to beat opponents one-on-one make him a serious threat.
If the Chelsea man can isolate Yoro and attack him directly, the defender could be in for a long afternoon at Stamford Bridge on Saturday.
