Premier League - Is There a Shift in the Back Four?

There are only two sides at the week end that used to back three. In the same game with wolves against brentford. And i think that's the lowest in a primalive week end for about four or five years. Ronneck hasn't touched it so far. I mean, because i remember venger did it in that season,. you know, a bit, which was a big departure. It can work often as a kind of shock theropy thing, but actually do it in a sustainable way is very difficult due to specialized players. O that mean, a lot of the players just, you know, have never grown up being a wing back or a outside centre back. Li
