With regards to covid and football, in hindsight, international travel for football looks like a bloody stupid thing. Nuno told the press at the weekend what an effect covid has had on the Wolves squad this season. Apparently the recent Burnley game is where it really caught up with them. Neves, Saiss, and Boly in particular have all caught it this season I believe, and Boly in particular is really suffering.
He's out of action now with long covid, apparently he's in a bad way, suffering heart palpatations and a general lack of energy that's rampant throughout the squad.
