Leicester City are still on track for automatic promotion to the Premier League, according to manager Nigel Pearson.
The City boss remains optimistic despite a run of games that has seen them win just one out of four and take four points out of a possible 12.
The next two games are going to be important for their promotion push as they face league leaders Cardiff City, at home, on Saturday and then in-form Hull, away, on Boxing Day.
"We are well in the shake-up," said Pearson. "It is very tight above us. I have a good handle on the perspective.
"It was a missed opportunity (against Millwall) but we are in and amongst it.
"We have two games (Cardiff and Hull) coming up, and, if we beat them, we can make a big impact because they are teams around us."
Pearson will be aware just how quickly the promotion picture can change and that is especially true during a hectic festive programme.
The games come thick and fast with four games between now and New Year's Day.
After City's clashes with Cardiff and Hull, they travel to Burnley, a week on Saturday, then face Huddersfield at home on New Year's Day.
In the games City have failed to win, they have enjoyed plenty of possession – just as it was at Millwall.
Pearson said that defeat was "a lost opportunity" and he will be hoping for results to match performances over the festive break.
The next four games for the Championship's top six are:
City: Cardiff (h), Hull (a), Burnley (a), Huddersfield (h)
Cardiff: City (a), Crystal Palace (h), Millwall (h), Birmingham (a)
Crystal Palace: Huddersfield (h), Cardiff (a), Nottm Forest (a), Wolves (h)
Middlesbrough: Leeds (a), Blackburn (h), Blackpool (h), Derby (a)
Hull: Derby (a), City (h), Leeds (h), Blackpool (a)
Millwall: Brighton (a), Barnsley (h), Cardiff (a), Bristol City (h)
