I agree that he should be timing his runs better given he has the pace to beat any defence but not sure why you felt the need to type a long reply by picking out a few offside moments. The one against Spurs was a close offside call, as opposed to being a blatant, well offside offence like some of the ones yesterday.
Even if teams play with a high line against us, we would still expect Werner or any of our other attackers to time their runs. Otherwise, would you say Vardy is lazy considering he's always been up there on the offside list? Leicester also don't always play on the break apart from when they face the Big 6 under Brendan Rodgers. Or what about Rashford? He's just 1 behind Werner on the offside count. Or what's your explanation that Mane is also up there?
You're really committed into this, aren't you? lol We have gone from talking about his misses to him being offside!
Not sure if there is any stat site out there that gives detailed info on offside. You might have to go look at individual matches instead.
What I've managed to find is Werner's offside per 90 mins stat is less this season compared to previous seasons:
2016/17 - 1.9
2017/18 - 1.6
2018/19 - 1.4
2019/20 - 1.4
2020/21 - 1
