West Ham were short-priced favourites for the Championship title before a ball was kicked and the signs are already looking pretty ominous for those hoping to lay down a marker.
The Hammers started slowly, failing to win any of their opening three games, but four straight wins have catapulted them to the top of the table on goal difference.
They were dumped out of the EFL Cup on Tuesday, losing 3-2 to Premier League Fulham, but have a derby to look forward to and a chance to get back on track.
Millwall finished third in last season's Championship and they should believe that they can at least force their way into the play-off places again.
However, injuries are taking their toll and Tuesday’s 2-2 draw with Middlesbrough ended a run of three straight Championship defeats.

Best Bet: West Ham to win @ 4/5
West Ham took time to adjust to life in the Championship, taking only two points from their first three games, but they are well and truly up and running now.
Nuno Espirito Santo's side have won their last four matches and last Friday's 6-0 drubbing of Wrexham at the London Stadium was further evidence that they have the best attacking options in the division.
Jarrod Bowen should be a Premier League player and Joel Piroe and Manor Solomon have settled in effortlessly.
With 16 goals scored in their last four games, it is hard to see how anyone in the division can live with the Hammers if they are on song and Millwall are being hampered by injuries.
Alfie Doughty, Casper De Norre and Mihailo Ivanovic remain sidelined through injury and they may have no choice but to field a similar side to the one that drew 2-2 at Boro in midweek.
While that looked a good point at the Riverside Stadium, Millwall had led 2-0 at half-time and Boro won the shot count 22-11. Allowing the Hammers a similar number of chances would be fatal.
Alternative Bet: Konstantinos Mavropanos anytime goalscorer @ 11/2
West Ham have an abundance of attacking talent but they also carry a serious threat from set-pieces, with the towering presence of Konstantinos Mavropanos causing most problems for the opposition.
Mavropanos already has three goals this season, having netted in wins over Wolves, Bolton and Wrexham, and this will be a physical battle which should play to his strengths.
The Greek international has had 12 shots in six league appearances, hitting the target five times, and could have another starring role to play.

West Ham have scored 18 goals across their last five matches and could bag a couple more against Millwall, who have kept only one clean sheet in six.
Bowen has scored four goals in his last four Championship appearances, with at least two shots on target in each.
A card could be calling for young Millwall midfielder Jenson Metcalfe, who has committed 17 fouls in seven league matches.
