Roma's midfield is the key to their success in the Italian Serie A this season. The core of the team, which includes the likes of Lorenzo Pellegrini and Miralem Pjanic, has been instrumental in securing four consecutive victories for the club.

Pellegrini, who joined Roma from Udinese last summer, has been a standout performer for the team so far this season. He has provided crucial assists and scored several important goals for the club. His work rate and tireless running have also helped him become one of the most dangerous attacking players on the pitch.

Miralem Pjanic, meanwhile, has been a calming influence in the middle of the park. His ability to read the game and make intelligent decisions has been crucial in helping Roma maintain control of matches. His passing accuracy and vision have also been exceptional, allowing him to create scoring opportunities for his teammates.

Both Pellegrini and Pjanic have shown that they can be relied upon in high-pressure situations. They have played an integral role in Roma's recent successes, and it will be interesting to see how they continue to perform as the season progresses.

Overall, Roma's midfield has been the driving force behind their strong start to the season. With such a talented core, it looks like they could go all the way to the top of the league.
