I don't think a couple of games removed from pre season a 6 mile run a week or so before their next match is going to be the death of any of them.
Could be a good team bonding exercise too. If I were ETH I'd be having a look at the players that are sulking about having to do it and putting a question mark over whether they're the sort of personalities that need to be at the club long term.
Plus Ronaldo sulking and waving his arms around on the run would be funny to see
It’s a bit of a simplistic way at looking at the result. It wasn’t the lack of running that lost them that game. Then there’s the statistic on an individual basis. Collectively they ran less, but what if the defenders covered a similar amount and the attackers/midfielders were slacking, as an example. If I’m a player I’m not going to be happy being called out on a lack of running if I’ve performed similarly to the opponent.
