Millen's View: Leicester home 2-0
Millen tried to match former England manager and Monty Burns lookalike Sven-Goran Eriksson with a bold 4-3-3 but changed to a 4-4-2 at the break with the scores level.
It was to prove a masterstoke as second-half goals from Brett Pitman and David Clarkson earned only our second home win in front of our own fans this season.
"You could say we got it wrong in the first half," admitted Millen. "But it was not so much about the tactics, it was more about our ball retention and inability to pass our way through Leicester, which was our biggest problem.
"Leicester have three very good central midfielders, who can hurt you if you allow them to have too much of the ball. I tried to match up with them and get Marvin Elliott to bomb on from midfield to support Jon Stead and get into the box.
"Unfortunately, when we did win the ball, we gave it back too easily and struggled to get our wide men into the game. We never got any crosses into the box for Marv to go and help Jon Stead and be dangerous.
"Tactically, it didn't work in the first half and we had to change it. It may be that the shape did not help us in that respect and I'll go away and analyse that on the video.
"You don't always get it right and, when you don't, the important thing is to recognise it and make the right changes. That is what I'm paid to do. In the second half, we have made changes and we have ended up coming out on top, which is brilliant.
"Putting Brett on gave us a bit more presence in the final third and I thought it evened the game up a bit. Goals change games and we scored the first one. Leicester are one of the form sides in the league and they didn't do too much wrong, but once we scored, I was confident we could hold on."
