What a load of bollocks. The English league is tough and the number of games, with cup competitions makes it very hard to succeed domestically and in Europe. Generally a club suffers in one or both. No winter break doesn't help either. The other European sides are rested and come back for the CL knockouts fresh, we go into them after a heavy run of fixtures and the third round of the FA Cup. And then League Cup semi's are played as well... Juve generally can coast domestically and prioritise Europe. So can Spanish teams. It's so much easier for them and then they can keep up their performance levels.
The prem has weakened in quality slightly and become more competitive but I do not believe we're tactically weaker than anywhere else.
it's not bollocks at all, English teams have always looked tactically inferior.
