I always back the top teams when we are talking about who is going to win this competition that is based on knock out and not a league form. The reality is that you may not know which of the teams that will end up winning it, but the likes of Chelsea, Manchester City and Liverpool are trying to win this trophy as it is one of the ways to prove that a team is the king of England.
There are other clubs such as Manchester United, Arsenal and Tottenham Hotspur, but their performances this season ain't showing that of a team that is ready to challenge for this honor.
When I look at Liverpool and Manchester City, for instance, I see two teams that has got the best defence in the league in terms of few goals conceded and this is something that you shouldn't be neglecting when talking about the English FA Cup.
