Ultimately yes but still i doubt allan would come knowing he would be nothing more than a rotational player
Allan would definitely come to Juve, because apart from the step up in terms of quality, he would also be aware that if he proves himself, he would definitely find a way into the starting eleven. Pogba is not going to be here past the next two seasons at best, and is probably gone this season at worst. Pirlo is likely going to say his last goodbye to us too in all likelihood, Romulo isn't featuring anytime soon. Why wouldn't a young, hungry and talented player refuse a move to the club if the club is interested? Lack of playing time is highly unlikely seeing our jam packed schedule.
Only if Allan became a regular at Juve. In which case we wouldn't be selling him any way.
Plus in 5 Years time Ronaldo will probably be worth less than Coman. Doesn't mean anything. It's about what you get in the years you actually own the player. And Khedira could succeed here.
That's the point though. Allan is likely to become a regular at Juve if he plays to potential, seeing the variables linked to the futures of the players I've mentioned in the post quoted above,.
Khedira is a backup, but not for Pirlo. If I had to choose one, I'd go with Allan, but Bepoe and Paratici are perhaps prioritising another position if this move is going through, and I'm thinking that's Darmian or another forward.
