Chelsea vs Borussia Dortmund: Jude Bellingham Questions Graham Potter’s Tactics After Enzo Fernandez’s Howler

• Jude Bellingham was left surprised by Chelsea's defending of Borussia Dortmund's goal
• Dortmund scored against the run of play to get an early advantage ahead of the second leg
• The defeat compounds Graham Potter's woes, with Chelsea failing to produce desired results

Borussia Dortmund's midfielder Jude Bellingham has appeared to question Chelsea's tactics after his side picked up a crucial first-leg advantage in the Champions League.

A Karim Adeyemi strike in the second half was enough to separate the two sides to set up an exciting return leg at Stamford Bridge in two weeks' time.

Chelsea failed to capitalise on their huge chunks of possession and chances. They hit the post once, had a ball cleared off the line, with Gregor Kobel pulling off other decent saves in what was a very frustrating night for Graham Potter.

The Chelsea boss is hanging by a thread after his side extended their winless run on the road to 9 games.

Adeyemi's counterattack

Bellingham, who is reportedly on Chelsea's shortlist for summer acquisitions, questioned why Chelsea gave Adeyemi a free pass to score the goal.

The Dortmund goal came from a turnover in possession after Chelsea's centre-backs went over for a corner. The Yellow Wall defended the set piece well before releasing Adeyemi, who only had Enzo Fernandez and Kepa Arrizabalaga in the Chelsea goal to beat.

Fernandez fails to stop counter

Fernandez failed to stop the German's burst forward, perhaps wary that a last-man offence could result in a direct red card. Adeyemi then rounded Arrizabalaga and passed the ball into an empty net.

Bellingham could not wrap his head around why Chelsea decided to leave only one man behind.

"I was surprised they left only one player back with the pace and power that Karim Adeyemi has," as quoted by CBS Sports Golazo.

Meanwhile, Sports Brief has reported that a section of the club's fans is yet to move on from Thomas Tuchel's dismissal. The German was sacked in early September after a Champions League loss to Dinamo Zagreb.

It was a shocking decision as Tuchel had led Chelsea to three titles in the 15 months he had been in charge.

Ahead of the game at Signal Iduna Park on February 16, Blues fans unveiled a huge banner of the former manager.
