Well that's just wrong
Up until the final games of last season he was a "false lw", positioned there in the formation but with license to come inside and play as a 10, hence him shooting on his right or setting up other's
In the last games of last season Klopp moved him to midfield as the most attacking player of the middle 3. Plan this season was for him behind the front 3, and that's where he played most
Klopp used a 4222 in a few games, notably West Ham away, but this is the exception not the rule
He certainly has never been a typical touchline hugging winger, that type of player isn't in fashion, as evidenced by Mane playing on the left and "no right foot" Salah playing on the right
Here's his heat map for when he played in the front 3 vs Maribor - the only time he reached the byline was to take corners lol, he doesn't even go near that corner of the pitch lol. Whereas a typical left footed left winger will be beating his man, going to the byline or into the box, whipping in crosses etc
Coutinho by comparison is coming inside and dictating play from the centre just as much as he is on the left side of the pitch
Here's the heatmap from the 1-1 draw vs Burnley when he played in midfield - Again clearly more central
and finally his total PL heat map after 14 games
