He's not going to outshine anyone, even Dier and Sanchez unless he goes back 5 years to the player Barcelona thought they were signing.
That's a huge ask let alone to come in and shine at it.
Once again - half the sentence and you make an opinon of it - disregarding rest of what I said.
1 year back, majority of fan base wanted to get rid of Dier - and for good reason given he had some bad bad games. But Conte saw a player he can salvage and salvage he did by bringing his best qualities out & hiding his mistakes
In same way, some of Lenglet qualities are world class whether you like it or not - even in worst 20/21 season, his passing & progressive stats were better than Bastoni.
IMO, as a start, Spurs will suit him almost too perfectly
Lenglet Weakness : Slow when running back, ball behind the defense struggles , he puts high risk tackles at times. All of his weakness gets exaggerated by Barca - they play high line, no defensive midfield, fullbacks who gets exploited time & again.
Seville (17/18) and we under Conte - dont play high line - play with 2 functional Defensive midfielders who screen well, defensively well organised and we drop back well. This means, potentially Lenglet doesnt have to deal with ball behind defense. Like Dier, his weakness can also be hidden to an extent.
No one knows how future will be - but with Lenglet , Conte has something good to work with.
