Arsenal's hopes of making it six wins from six in the Premier League have suffered a blow before a ball has even been kicked on Sunday, with Mikel Arteta revealing that Oleksandr Zinchenko hasn't trained in the build-up to today's meeting with Manchester United.

The Ukrainian has been a big hit at the Emirates since joining from Manchester City during the summer, averaging an impressive 7.30 rating from WhoScored for his performances in the opening three fixtures.

However, he picked up an injury in training and subsequently missed the games against Fulham and Aston Villa, which saw the Gunners scrape 2-1 wins, looking far less impressive than they did in previous performances.

Unfortunately, it seems as if the 25-year-old won't be fit to feature in Sunday's game at Old Trafford, as Arteta confirmed that he has not been able to train with the team this week.

Kieran Tierney looks likely to deputise at left-back - with the Scotland international having averaged a far less impressive 6.21 rating from WhoScored in his Premier League appearances this term.

This suggests that Arsenal will be far weaker down the left-hand side, and considering Jadon Sancho has started the season well for United with two goals as a right-winger, while Antony will also be in line for his first appearance, this could be an area which United can exploit.

Although Zinchenko's injury doesn't appear to be too serious, it is undoubtedly a big blow if he misses the game against Erik ten Hag's side, as Arsenal will be desperate to maintain their 100% record against their old foe.

The Ukraine international has plenty of experience in winning, and Aaron Ramsdale praised the shift in mentality which has been aided by the arrival of Zinchenko and Gabriel Jesus from Manchester City.

He said: "It's crazy how our mentality has changed from the end of last season. We're more ruthless. We saw how close we came last season [just missing out on a Champions League place to Tottenham Hotspur]. It took a few weeks to get over. It hurt more because it was the others down the road. Zinchenko and Jesus know how to win."

Pep Guardiola also described Zinchenko as an "exceptional" talent during his time at the Etihad, so Arsenal did brilliantly to sign him this summer, and Arteta will be cursing his luck that the versatile Ukrainian seemingly won't be available for the Gunners' toughest game of the season so far on Sunday.
