I think it's too early to say that Ranieri is a bad coach at the moment. Because Ranieri has only coached Roma for about 2 months, so in my opinion it is natural that Ranieri has not been able to have a significant positive impact on Roma. Because of course Ranieri also needs to adapt first and get to know the character of the players in Rome to be able to implement his strategy perfectly. Apart from that, I personally think that currently Roma is starting to have some pretty good developments in Ranieri's hands. The proof is that a few days ago Roma managed to beat Lazio quite decisively with a score of 2-0. This is certainly quite good progress in my opinion. Apart from that, if we look at Roma's record in their last 5 matches. As a result, Roma was able to win 3 matches, draw 1 and lose 1. If you look at this, I think Ranieri has really made quite a good change for Roma, even though it's not yet significant. Therefore, I believe Ranieri can provide quite good results for Roma this season. And I don't think we need to compare Ranieri's coaching period at Leicester with now. Because it is clear that the situation when he coached Leicester was completely different from when he coached Roma now.
Slowly, Claudio Ranieri has succeeded in having a positive impact on AS Roma after winning two of the last three matches in all competitions from defeating Sampdoria at Copa Italia, won from Parma, Lazio and being draw Milan at domestic league matches.
Arriving as Roma manager after sacking their previous manager not easily for Claudio Ranieri because must adapt well with previous teams composition but waiting how Roma's management keep loyal for signing top players in this window transfer opening.
Upcoming several matches later, AS Roma should easy get three points because facing the mediocre teams and improving current standings still 10th place and moving to the UEFA Champion League spot behind 9 points left from Juventus. I think Roma under Claudio Ranieri head coach have opportunity for securing top standings position place and opportunity reach the Champion League spot standings in this season.
