"It's been great football to watch," Silvestre told Manchester United Radio. "The boss encourages the side to play attacking football, which suits the fans and the English game.
"I've been particularly happy with how the team have been performing at the back. There's a good understanding between the players, whoever's been playing there. I think we deserve to be top of the league because we don't concede many goals."
Silvestre, who's hoping to play a major role in United's bid for silverware, confirmed he emerged unscathed from his first outing in the senior squad for almost seven months.
"Physically I felt quite good [against Roma]," he said. "Even the day after I was fine.
"Walking out of the tunnel before the game was very special and I was really looking forward to getting back on the pitch.
"It's always a pleasure to come back from injuries, especially in front of a full house on a European night.
"I enjoyed the match from the first minute until the last."
