On this about Carlo Ancelotti you're very decent on him. He's one those few coaches with a quiet character on the pitch, very calculative of the game to get results as the opportunity presents. By experience he's far weigh above Mikel Arteta league and it's just common that Arteta can only give his best of strategies in this game and hope to be lucky. Because in all ramifications Real Madrid seems to be ahead of Arsenal having won this UCL trophy as many times as can be recalled meanwhile Arsenal haven't found a season to their name.
There is no doubt about the exceptional record of Ancelotti and if its by the coach records, Real Madrid will win the match but a lot other things will determine the outcome of the match different from the coach a lone. Barcelona seems more motivated than Real Madrid at this time and unless anything changes, they may be at advantage to win the match but Real Madrid does not lose finals easily which is another factor to consider. Nevertheless, this year may be one of the toughest finals we will be seeing.
You know I wanted to mention about the aspect of Real Madrid hardly losing in finals but then you said it, and that's what am lurking on for Real Madrid in this meeting with Barcelona. I think it will be very embarrassing for not just Ancelotti but to the entire team that in three meetings with Barcelona they could figure out one single win as consolation to the previous two humiliating losses. I expect it to be a tough clash for sure am still rooting for RM to win this finals despite how motivated Barcelona may be looking right now.
