It depends on what you define as 'error'. The issue is because of Lindelof's passive and non-engaging/non-committal style of defending, he may not 'make' an error but the team suffers because there is not an action taken, which can positively affect the team. This ends up being really weak individual play, regardless of the system, coaching and/or instructions and imo is categorically an error because in-game participation plays are not a binary measure i.e like stats are. With Lindelof, it's like nothing ventured, nothing gained.
Below are two time-stamped examples and an almost, hilarious carbon copy representation (against the same player as well!) of Lindelof's passive tendencies, which has given plenty of people, fuel to critique on. These are not examples picked from some random game or something that has only happened once or twice; it's something he's shown dozens and dozens of times over 200+ games.
Both times, he's allowed Watkins to dribble 10-30 yards into the box with little to no pressure and even got himself done. Both incidents, which could have lead to a goal conceded in each game. Now of course last week he redeemed it with a brilliant headed clearance but his traits have always been there. For me, I find it plenty logical to be commenting on these individual plays and expecting more but for some, it's seen as 'he's not made an error and he was delaying the player'. Yet this criticism is then downplayed as being overly critical or a hater, 'you're not seeing his strengths'. And now some people are extrapolating his latest form, which is likely due to him maturing as a player, knowing he has to step up and being ultra fresh, then hyping him beyond normal standards. Better passer than Martinez, would start ahead of a fit Varane, best third centre back in the league, his previous 200+ games/6 years of his career and inconsistency was down to Maguire/Ole/Mourinho/Smalling/the tea lady, 'he's been really good this season when called upon (let's forget the first 3-4 months)' etc. Proper mind boggling stuff.
With that all said, if he keeps it up and continues to be more proactive and effective, then we only need to comment on the present because maybe he does have a future here.
