I think calling it counter attack is an oversimplification, but it's clear that we play fast, direct football with the ball, so it ends up kinda looking look a counter attacking strategy.
Essentially, Ole's tactics is a preference to play direct with balls in behind. Him and the players have made numerous comments about not wanting possession for possession sakes, and it's evident in our play. We frequently look to get our front players in behind with through balls. We don't create overloads in wide areas, our wide forwards don't tend to wait for an overlap from the full backs, who themselves stay deeper, they look to get into the box. It's part of the reason we win so many penalties, because we constantly get players on the ball into the box. Bruno exemplifies this strategy because he gives the ball away 10 times a game by always looking for the killer pass. A few a game come off and so we score goals, but we dont have high possession stats.
As a result, it looks like and in a way becomes a counter attacking strategy, because we often don't have the ball so we're deeper as a team. We definitely don't recycle possession very much through midfield, but we can punish teams who play a high line. Either with a direct pass in behind, or to feet into Bruno or Martial who are high up and then look to play someone through within a couple passes.
I don't know what the stats say but it's evident from watching. The statistics might be skewed by the fact we're often the favourites and so will face teams camped in their own half anyway. And we also flaff about with it in defence too much, which is not something particularly associated with a counter attacking team. We're certainly not Conte level of counter attack, but yeah, we're a direct, fast side.
It actually really annoys me that we insist on playing out from defence despite this, and despite being fairly bad at it. We spend plenty of time flaffing about with it in defence, which seems pointless as when we get the ball into midfield we no longer look to keep possession and go direct. I suppose if we had a ball playing DM we might find a nice balance.
