Bug offside proclub FIFA20?


Club Supporter
Hi guys, I would like your opinion on this action that happened during a pro club game.
My team and I were wondering if it's a fifa bug or a cheat.
I am part of the team that conceded the goal, and we think that the player who scored, at the moment of the long throw of the defender, is offside; but FIFA hasn't whistled it ... To understand this, look at the radar too ..
I apologize for my english and offtopic
