Indeed and LVG highlighted this in the post match interview.
LVG basically was kicking himself for taking off Fellaini and I doubt he'll be doing that in a hurry, again.
This is why, for LVG, after Rooney and maybe DDG, Fellaini is the most important player and fans need to get used to this.
LVG's main objective is to concede zero goals. This enables us to get a draw (if we don't score) or 1-0 win (assuming that we score 1 goal, in line with our average).
I think that the main reason we lost so many games in December was because LVG was bowing to pressure to attack and this completely threw his tactic out of the window, which meant that we were conceding more goals, but needed to score ourselves - which we are unable to do against decent sides.
Summary: I don't like Fellaini, only because he enforces LVGs very negative tactic of trying to win games 1-0. BUT LVG needs Fellaini to enforce his negative tactic.
We are conceeding awful lot goals with Fellaini in the side, stop imagining things.
Ever since he started his "run" against Wolfsburg our defence looks terrible, mostly because we don't have any control in midfield when he plays.
Since he started his run against Wolfsburg, with him as a starter we conceeded 3 against wolfsburg, 2 against Bournemouth, 2 against Norwich, 2 against Stoke, 3 vs Newcastle, and one against Derby. He wasn't on the pitch/was substitued only before Wolfsburg's third goal, all other goals I mentioned we conceeded while he was on the pitch. We kept the clean sheet with him in the team only against Liverpool, game in which de Gea won MOTM, and home vs fecking West Ham - the game we haven't scored either.
The team is absolutely terrible defensively when he is in the team, we don't dominate games with him because he is no central midfielder.
At least before we started playing him again our defence looked good, and we kind of dominated games, even though the problems in attack were the same. But at least we weren't conceeding lot, and our defenders actually looked good. Before his first start in december against West Ham we conceeded just two goals in 6 games, after that he started playing and we conceeded 6 goals in 4 games. Then again, he was benched for two games in PL and we conceeded one goal. In the next game he started we conceeded 3 vs Newcastle. Admittedly, in next two games we haven't conceeded with him on the pitch, but we were absolutely terrible in those two games(Liverpool and Soton) and could have conceeded at least goal or two against Liverpool if it wasn't for de Gea.
And those 1:0 or 0:0 results with Fellaini playing are obviously something you just invented considering just one 1:0 and two 0:0s happened with Fellaini as a starter, and both of those 0:0 were terrible result considering they were against West Ham and Southampton at Old Trafford.
