So you think it's a 'tactic' to take heavy touches and misplace passes?

It's pretty wild to attribute faults from an out of form player to a Wenger tactic or instruction. You're taking form and confidence out of the equation.
He doesn't instruct them to pass slower. In post match interviews he'll often say we didn't move the ball quick enough and the usual 'we lacked a bit of sharpness' or 'heavy legs' so that should be enough indication that he hasn't told them to play at a slower pace. I've said this before. It's pretty hard to remain composed, calm but play at a lightening fast pace and Wenger will often to refer to the players needing to be calm and composed when facing a stubborn defence. That's why I think the players can often get stuck in that one tempo phase of just moving the ball slowly. I don't think it's intentional but when we haven't got the confidence to play at a quicker pace because we've had some wayward passes or heavy touches....you get what we saw in the first half. That's my theory on why we're not playing to our full potential.
I can accept if the way we prepare for games mentally and what we do in training has the squad misfiring but that's different to tactics. It's something you keep muddling up.
You also may need to stop listening to the brainless English pundits on MOTD and BT Sports. That lack of footballing brain bollocks and Theo being at his best when not thinking is utter nonsense. The scorpion kick goal Giroud scored came about through pure instinct and just reacting to how the ball arrived. Most strikers react that way hence why they call it a 'strikers instinct'.
