Chelsea fans might be elated about an impressive comeback from the Blues to beat Borussia Dortmund at Stamford Bridge following a loss in the first leg. However, they weren't pleased with every player on the pitch, particularly Christian Pulisic.The USA international came on in the 82nd minute and did nothing for the 15 minutes - injury time included - he spent running around the pitch. He was expected to be Raheem Sterling's replacement on the edge of Dortmund's defensive line, dashing into space to enhance counter-attacks.However, the Chelsea forward had little interest in adding to the scoresheet, opting to consistently slow counter-attacks down instead. Although he spent a short time on the pitch, fans took notice of his rather drab performance and took to Twitter to slam him.Here is a selection of their tweets:#PotterIN@user144410That Pulisic cameo was disgraceful. He should be the 1st person we offload in the summer. I can’t even think of ONE thing he offers.11That Pulisic cameo was disgraceful. He should be the 1st person we offload in the summer.

This included a twice-taken penalty to relieve the pressure on manager Graham Potter.After winning only three of their previous 16 matches, Chelsea found themselves in a precarious position. They've dropped to 10th in the Premier League and exited both domestic cups early. However, the team's expensive collection of stars came through in time to keep their hopes of a third European Cup alive.Despite arriving in England on the back of a 10-game winning streak in all competitions, Dortmund posed little attacking threat in the first half. This was with the exception of a Marco Reus free-kick that Kepa Arrizabalaga did brilliantly to palm to safety.Chances continued to come and go at the other end. The home fans finally had something to cheer about just before halftime when Sterling dribbled past Reus and scored.Havertz's penalty early in the second half meant Potter's men scored more than once for the first time since December 27. The German international needed two spot-kicks to make his mark, and his first penalty came back off the post.However, VAR came to Chelsea's rescue once more as Dortmund were further punished for encroaching. Havertz coolly slotted the ball into the same corner, this time finding the back of the net.The Blues tried to protect their lead in the final quarter, relying on their defense to bail them out as BVB threatened. They held firm until the very end, keeping a clean sheet and overturning the deficit of the first leg with a 2-0 win at home.
