I was being a bit facetious but your post seemed very reactionary the second we conceded a goal. If you look at the league table we've the best defensive record by a long way in the division.
I don't think our defence is the issue. We've looked a little toothless up front for a number of games and very slow and methodical in the build up.
I'm not going to start criticising Enzo just yet though. He's been in the job for less than 4 months. Rome wasn't built in a day. We're top of the league. Given time I'm sure we'll start developing plan B and plan C, but for now we're top of the league and what he's done has largely worked.
Teams often go through patches in a league where they drop off for a bit. Let's hope we recapture a bit of the form we had at the start of the league again soon. Maybe over January, and definitely over the summer we'll need to invest if we want to compete in the Premier League but for now we're doing alright this season.
If you support Leicester you have to take the bad with the good. We never have a season where we look good all season (2015/16 being the exception).
I remember people complaining in the 2013/14 season when we lost 2 and drew 1 in consecutive games. There is always a bad patch, but I have faith Enzo will turn it around.
We may have made a number of signings over the summer, but I don't think we've players to match his system quite yet, but results wise I think we'll allow him a little leeway for now...
