I agree with you. If a teams gradually becomes stronger. Then it has a long shelf life. The way the Roma team has performed in the last two seasons is absolutely commendable. Their squad was not very strong. Still, they managed to perform quite well. Now if Roma management prepares a decent fund to bring in new players and strengthen the team. Then maybe next season Roma team will aim to win the title. But the problem is that Roma management is not interested in building the team by spending a lot of money.
Building a strong team must cost money. A team can never be made strong and beautiful without spending money. And yes in this case 'Roma' is not at all interested in spending any money on the team due to which Roma cannot win the title despite being very strong. I think next season Roma need to strengthen the squad to win the title. And they must bring in stars to strengthen this squat. If Roma can bring in stars and strengthen the management then surely they can win the title next season.
