Robson lists Chelsea's January transfer needs (1:12)

With the January transfer approaching, Stewart Robson details the areas where Chelsea can add reinforcements. (1:12)

Christian Pulisic is in his first season at Chelsea, following a $73 million move from Borussia Dortmund. The campaign's first half saw the 21-year-old U.S. international make 22 appearances in all competitions, scoring six goals and claiming five assists.

ESPN will continue to assess Pulisic's performances, with updates to this feature being added after every Chelsea match.

Pulisic's previous games (first to last): Aug. 11 - Dec. 29 | Brighton | Nottingham Forest | Burnley | Newcastle | Arsenal

Opponent: Hull (2-1; Jan. 25, FA Cup)

How he performed out of 10: No rating. Pulisic missed his side's FA Cup fourth round win at Championship club Hull as he continues to recover from injury. Following the midweek draw against Arsenal, Chelsea manager Frank Lampard said of the midfielder's timetable for return: "It will probably be the other end of the February break but he is getting better and he is not that far away."

Opponent: Arsenal (2-2; Jan. 21, Premier League)

How he performed out of 10: No rating. Pulisic remains out with the groin injury he suffered on Jan. 10, which will keep him out until mid-February. Three games in eight days, against Manchester United, Tottenham and Bayern Munich, beginning on Feb. 17 mean Chelsea will be keen to get the U.S. international up to full fitness as soon as possible.

Opponent: Newcastle (0-1; Jan. 18, Premier League)

How he performed out of 10: No rating. Pulisic failed to return following his groin injury suffered on Jan. 10. On Friday, it was reported he'd be out until "mid-February" given the rehabilitation and rest required. It's possible he returns to fitness in time for Chelsea's visit of Manchester United on Feb. 17.

Opponent: Burnley (3-0; Jan. 11, Premier League)

How he performed out of 10: No rating. Pulisic was not named to the Blues squad after picking up an injury in training during the week as Chelsea cruised to a win over Burnley. He has another week to recover from his injury before the Blues travel to Newcastle for their Premier League clash on Saturday, Jan. 18.

Opponent: Nottingham Forest (2-0; Jan. 5, FA Cup)

How he performed out of 10: No rating. Pulisic was not named to the Blues squad in a comfortable win at Stamford Bridge that sees them move on to the FA Cup fourth round. The U.S. international will get his next chance to impress on Saturday as Chelsea host Burnley in the Premier League.

Opponent: Brighton (1-1; Jan. 1, Premier League)

How he performed out of 10: 6. It was another lacklustre performance from Chelsea, and they were oftentimes downright dysfunctional. Pulisic didn't stand out from that assessment, for better or worse. He enjoyed moments of quick interplay and clever close control that created opportunities, but his finishing was lacking and at times his decision-making was labourious.

Highlights: The U.S. international's quick feet were a ray of hope throughout his 66-minute performance. His four take-ons were more than fellow attackers Tammy Abraham and Willian combined in his time on the pitch, creating a pair of chances in the first half and leading to three shots in the second. His passing wasn't as sharp as it should've been, but he did dispatch a couple of clever balls that led to chances, one scooped effort to send Abraham into the area and another to Mason Mount that put the Blues in position to enjoy an extended spell of position in and around the Brighton box.

Lowlights: His decision-making in transition was at times poor, which manifested itself in a passing percentage of 77% -- better than only Abraham and N'Golo Kante. He was impatient after beating two defenders in the first half, sending in a hopeful cross forward when he had no players forward with him. The shots he created for himself through clever footwork in the second half let him down; they were from positions and distances that should've yielded more than two missed targets and one simple save from Mat Ryan.

While the lowlights paint a picture of nothing but doom and gloom from Pulisic, no one from the West London club looked particularly impressive. Pulisic was one of 11 Blues dressed in black whose performances were as dark as their kits.
