Paul Pogba is a talent to have in your team and he will definitely start up because he has been up with his game even when he was on ban from football as he seasonally have some trainings and fitness because that's what keeps you fitted as a professional player cause lack of training after all this time would have made him a little dusty which he will get over but staying in check is what he has been doing so he will definitely see the starting lineup.
He wouldn't have settled for Monaco if they haven't promised to start him, there might be some other club high ranking ones but probably the condition wasn't a start, they can buy him and use him as investment which is why I think he settled for Monaco to do some wonderful job. He was even smart all those times, he was training even when he was banned from playing and to make it worse, before the ban Manchester United terminated his contract immediately.
He might has lose some money and lifestyle in that two yeses but if he is determined and to do something better for himself before he retire, this is the best time to show all he has at least to become the best player that was suspended and later came back to actions to make Monaco win their domestic league and came back to Champions league, even if the team doesn't stand a chance to win the Champions League, if he can do that for Monaco, more deals will come.
