Juventus is quite active in targeting the players they want to recruit, but Juventus has a just barely budget so it cannot recruit players who are expensive. It can only negotiate with the club and players at a price it can afford if the club does not agree with Juventus' offer. Juventus can't do anything other than look for players who are cheaper but have good performance, even though finding players with good performance and cheap is very difficult unless they recruit players from lower level clubs.
Recruiting players from lower level clubs does not have a very high market value, but Thiago Motta must look at the potential he has well before deciding to recruit the player and see what his track record is. If the coach feels he is able to hone him, then Juventus can look for players at low prices but with a note. The coach can accept it and build the players' performance well.
Even if they are lucky, I think they can get cheap players but with good enough quality or maybe their talent is not yet visible. Juventus' limited budget is an obstacle for them because they cannot recruit players whose talents are clearly visible. but what you say is true, Juventun can't do anything but look for cheaper players to help their performance be better, as long as they don't recruit the wrong players maybe it can help their performance.
Thiago Motta, like it or not, has to be able to utilize the available budget, so he can recruit players who are of low value but he must be able to see that the player really has brilliant talent, so when this can be seen, Thiago Motta just needs to hone the player and become a Juventus star. , even though it takes time, I am sure that Thiago Motta's adaptability can make each other's training process easier.
I know this is a difficult condition for Juventus, they cannot recruit expensive, talented players and are forced to recruit cheap players, but with more caution, they have to recruit players who have hidden talent and that is not an easy thing, but at least you can see how these players play and what kind of speed is it? If the coach feels that the player's performance can be changed to be better then Juventus is lucky to get him at a cheap price, many players have hidden talents. If the coach has extraordinary skills he can turn ordinary players into great players.
I think Thiago Motta can overcome this, the fact is that when he coached Bologna, who didn't have great players, he was able to hone the players performance well and compete with the top clubs in Serie A. So I think he can do the same thing if he hones the players abilities Juventus will recruit, but yes, it takes time and Juventus must be more patient if they want the players performance to improve significantly.
