Chelsea 4-4 Ajax: 5 Talking Points & Tactical Analysis | Champions League 2019-20 

#2 Chelsea's full-backs were all over the place

Marcos Alonso committed a couple of blunders against Ajax

From the tactical perspective, it'd have been wiser of Frank Lampard to hand a start to Emerson and Reece James down either side. This so, because both of them can handle, track and trace a pacy Ajax side better than the other pair.

While it was important to have Azpilicueta as a leader in such an important game, he could have plied his trade at left back. The Chelsea skipper, much maligned this season for his displays, gave away a cheap foul that lead to the opening goal of the night.

Further, he failed to time his tackles and was often beaten by the interplay between the midfielders and Promes. He rushed way too early in order to catch up, but often ended up digging his own grave.

Alonso meanwhile, was levels below the standard produced in the match on an overall note. For starters, he never ever caught up with Ziyech, almost as if the winger was given a head-start throughout the game down the right.

He gave away a silly foul that led to the own goal from Kepa. Why on Earth would one lunge in with the opponent player facing the opposite down, in a wide position? Further, he was nowhere near Ziyech when the cross came in for Promes.

On an evening where the Blues' center-backs were determined and focused, their wide defenders just totally let the team down.
