From what I can gather, people struggle to have balanced views on our players in general and Paul Pogba in particular. Especially if we lose a game and a player hasn't done anything amazing individually, then he was "abysmal" according to some in here. Also the converse if we win and they pull off a memorable moment, then they were magnificent and all else gets masked. There's no balance in the arguments, just raw emotions.
The above goes doubly for Pogba because he is a high-profile, high-salary, polarising player. The final is prime example of that. Pogba played in a 2-man pivot with McTominay and according to the heat maps he was also the deeper of the two midfielders, most often asked to bring the ball out of the defence and shield the back 4. As
@Roane explained, he had the most touches, most passes/long balls and the highest % of accurate passes out of any midfielder, as well as the most interceptions out of anyone on the pitch including defenders. He had 0 dribbles attempted (to McTominay's 6) because he played the type of game most often
not associated with Pogba; the measured disciplined game of a DM or deep playmaker. We (rightfully) lambaste him for taking players on and losing position in dangerous areas when he plays in that position, and now that he does exactly that we criticize him for not having enough impact.
The way I see it people are throwing their toys out of the pram because we lost a final to an inferior team and one of our star players didn't pull something magical out of the hat, despite literally playing in Fred's position. Again, it's an emotional rather than logical response. Did he have an amazing game? No, admittedly Villarreal made it easy for him by sitting deep, not contesting the midfield much and not really pressing. Did he have a bad game? Again no, he did the job he had to do: bring the ball out, keep it moving and protect the back 4 when needed.
His job was not to put a goal on a plate for the forwards, or to take players on. If it is anyone's, I'd argue that's Bruno's job playing the most advanced, free-roaming #10 role with no other responsibilities. We had effectively 4 offensive players (out of 10 outfield players) on the pitch who, despite us having %60+ possession and complete dominance in midfield, they failed to create any link-ups, combinations, 1-2s or dribbles to open up the Villarreal defence. Thus only managed 2 shots on target for the whole game but that's not on Pogba though, that's on the 4 attackers.
