It's obviously had to predict who will perform best in these unprecedented circumstances. We are a better team than them clearly, but we were very subdued in that Olympiakos game. That could be more to do with the uncertainty around the virus though, now we know they will only play against players who have tested negative, in an environment that is doing its utmost to ensure the safety of the players.
I think the teams who do best in this period will be the best conditioned ones, who pick up the least injuries. It's going to be so tough to a) player at full capacity on such limited preparation and b) playing this amount of games in such a short time span. What gives me confidence is that we have arguably the best fitness team (in large part for how closely integrated they are into the coaching) in the league. It will be tough with a small squad but if we can keep everyone fit, fresh and sharp it could also be an advantage.
West Ham have a terrible injury record in recent years as it is, so hard to imagine they will be in tip top shape. We will see I guess!
