Alex Oxlade-Chamberlain's performance against Barcelona will be remembered mostly for the glaring opportunity he missed to put Arsenal in front in the first half.
However, according to the Daily Mail, another moment in that disappointing 2-0 defeat looks set to be more pivotal to the young winger's season. It is believed the 22-year-old suffered knee ligament damage after his high-speed clash with Javier Mascherano and could be out for the remaining three months of the season.
Following the collision, which saw Mascherano get to the ball a fraction of a second before Oxlade-Chamberlain, the England international received lengthy treatment from the Arsenal physio and was able to carry on until half-time.
He even emerged from the tunnel for the second period but it soon became clear he was unable to carry on. Theo Walcott replaced him and it appears that could be the last time he takes the field in the current campaign.
The same report says Oxlade-Chamberlain may have also suffered ankle damage in the same challenge although there is nothing to suggest that he caused more damage by soldiering on until the 50th minute.
Oxlade-Chamberlain will undergo scans at Arsenal's London Colney today, which could yet show that there has been no significant damage. However, he will definitely miss Sunday's trip to Manchester United and all the signs appear to point towards something serious.
He was seen leaving the Emirates on Tuesday night on crutches with his right leg heavily strapped up. It is not just a major concern for Arsene Wenger but for England boss Roy Hodgson, too.
Hodgson is a big fan of the former Southampton star and took him to the World Cup in 2014 regardless of the fact he was suffering from an injury. However, he is unlikely to take such a gamble if Oxlade-Chamberlain doesn't play a part in England’s friendlies against Germany and Holland next month, which will be key to deciding tactics and formations ahead of the tournament.
He, of course, did not play in the World Cup in Brazil and missing the European Championships will be a massive blow for the man himself. Likewise, it will also see him miss out on what promises to be an exciting and historical end to the season.
Arsenal are narrow favourites to win the title this season but face tough tests away to Manchester United and Tottenham over the next two weekends. Wenger can call upon Walcott, Danny Welbeck and Joel Campbell to replace Oxlade-Chamberlain, but the Frenchman needs a full-strength side if he is to win a fourth Premier League title.
