When he came on today he played as the left sided attacker. From all our players i would prefer Ronaldo, Rashford, Sancho, Martial and Pogba over Lingard to start a game from that position.
Ronaldo will start as the most forward attacker, Sancho can play on the right and Pogba can play as midfielder. Martial can play as the striker.
The attacking midfielder position is Bruno his position and i would also prefer van der Beek or Pogba there over Lingard.
On the right side Greenwood and Sancho are players that i prefer to start over Lingard. Rashford has also started games from there, he is a better player than Lingard too.
For me Lingard is the second or third option subsitution for almost all front position. Usually a position taken by a young talented player but Lingard wants to stay (im sure there was interest in him since he did great at West Ham) and take that squad role. It does take away minutes from Diallo for example, i would still prefer to see him sold for a good amount of money to a club where he could start every week. That money will help getting an midfielder to replace Matic.
So no, he does not deserve to start. Maybe some smaller games or to rest other players but at all the position he can play at there are multiple better options to start.
