AS Roma take their 100 percent record to unbeaten Inter Milan on Saturday in a Serie A game featuring two sides who have undergone a startling transformation under new leadership this season.Roma have won all six games under Frenchman Rudi Garcia, who inherited a squad in disarray and has quickly turned them into potential title winners.Inter’s decision to hire Walter Mazzarri as coach has also paid off with the new boss, who enjoys the rare privilege of having never been sacked, performing wonders on a team that lost 16 league matches last season.Roma, who lead the table with 18 points, have the best attack and defence in the league while Inter, four points behind in fourth, are the second best in both departments.Both coaches have started by shoring up patchy defences.Roma, whose cavalier attitude under Zdenek Zeman last season left them with one of the worst defensive records in the league, have conceded only one goal in their opening six matches.Morocco defender Mehdi Benatia has proved an outstanding signing from Udinese and Brazilian fullback Maicon has enjoyed a new lease of life following his move from Manchester City.Ivorian forward Gervinho, who joined from Arsenal, has also found a second wind while captain Francesco Totti, 37 and in his 22nd season at the club, is as influential as ever. The team have scored 17 goals already, including five against hapless Bologna last Sunday.
