Sometimes it can (The Burnley paradime- great blocking and very good at headed goals tends to break it) but in general it's a good model to use.
They are just nowhere near good enough defensively though. I was thinking this in the car on the way home. That Liverpool defeat, if he had even a vaguely competent defence, who know to whack a ball clear in the box when it drops (rather than Dier and Rodon dummying it, and Lloris not pushing it out for a corner against the smallest team in the league) they probably scumbag an undeserved 1-0 win there and it's a classic Mourinho performance. But his defenders just aren't anywhere near good enough.
He hasn't helped himself, playing Dier over Alderweirld and Sanchez. But essentially Spurs gambled on themselves having top class players who just needed some tactical arranging into shape. What you see is they had decent players, made to look top class for a time under Pochettino, and Mourinho's model only really works with excellent defenders. He plays a game of fine margins, and they are nowhere near.
The worry for them, is this is like the Mourinho golden period and it only gets worse from here. You factor in fairly acute financial troubles to come and there are a lot of alarm bells for me if I'm a Spurs fan. They should have been competing to win the league. City have stormed through but they'd got themselves into a great position, and you never know what happens with pressure. They've completely bottled it.
