Atletico Madrid expose Barcelona’s left-side defensive weakness in opening 10 minutes

Atletico Madrid needed only 10 minutes to identify Barcelona’s main defensive vulnerability, repeatedly targeting the left side where Joao Cancelo was operating and creating three clear chances from the same area.

According to Sport, the Portuguese full-back struggled to judge when to advance and press his opponent and when to remain in his defensive position. Atletico, coached by Diego Simeone, quickly recognised the difficulty and made that flank their principal route of attack from the start.

The first warning came when Julian Alvarez found himself in a one-on-one situation with a defender after Atletico exploited the space on Barcelona’s left. Cancelo failed to deal with the situation effectively, allowing the Argentina forward to create a dangerous opening.

Atletico returned to the same area for their second attempt. Their pressure produced a corner, which nearly resulted in the opening goal. Marc Pubill’s effort struck the post, underlining how effectively the Madrid side had identified a route through which they could trouble Hansi Flick’s team.

Kang-in Lee was described as the main source of the problems Barcelona faced, while Cancelo carried much of the defensive burden created by those issues.

The third attack from the flank brought a more damaging outcome. Cancelo was again caught in a difficult position after choosing the wrong moment to move towards his opponent. Alvarez took advantage, finding Giuliano Simeone, who finished the move to put Atletico Madrid ahead.

Three major chances had been created through the same channel within 10 minutes. The issue was not limited to individual mistakes, however, with Atletico also benefiting from a lack of coordination in Barcelona’s defensive structure.

The clearest indication of the concern came immediately after the goal. Barcelona goalkeeper Joan Garcia went straight to Cancelo, held him and began explaining the errors he believed the defender had made.

Garcia attempted to correct Cancelo’s positioning, aware that Atletico were being given considerable freedom to attack down that side. Their exchange reflected the anxiety generated by Barcelona’s early performance, with Cancelo’s significant attacking qualities unable to compensate for his difficulties against an opponent that had deliberately prepared to target his position.

Cancelo committed a fourth error in the first half that could have led to Atletico’s second goal. Under pressure from the Madrid side, he lost possession in a defensive area and the move once again ended with a shot from Alvarez. Garcia managed to save the effort between his legs, although he appeared to do so with considerable difficulty.
