Austria Wien W Overview

Chelsea may be left to rue a massive missed opportunity in the transfer market as Fermin Lopez continues his sensational rise at Barcelona. The Spanish midfielder, who has become a focal point for Hansi Flick, was reportedly available to the Blues last summer, but a deal collapsed over a valuation dispute.

Bruno Guimaraes has offered a fascinating insight into the mentality of Mikel Arteta, describing the Arsenal manager as "very obsessed" with continuous improvement. The Brazilian midfielder, who arrived in North London this summer, believes the Spaniard's relentless drive is the primary catalyst behind the Gunners' perfect start to their Premier League title defence.

Chelsea suffered a 2-1 defeat to Arsenal at Emirates Stadium after finishing the match with two natural right-backs in midfield despite a £349m summer spend. Questions over squad depth persist as manager Xabi Alonso prepares his side to bounce back in upcoming fixtures.

Chelsea forward Morgan Rogers has insisted that the club's long-term trajectory remains positive despite suffering their first defeat of the Xabi Alonso era. The Blues saw their winning streak snapped at the Emirates Stadium, but Rogers is adamant that the squad is still in a period of significant transition and growth.
