Former Leeds United striker Steve Morison has promised to take the game to his former club when he faces them with Millwall this weekend.
The big battle at the New Den will be in central midfield, and Millwall are coming to terms with the exit of George Saville.
Saville left to sign with Middlesbrough at the loan deadline, moving to Teesside in a deal which will see Boro pay £8 million in January.
As they have shown so far, they didn't need him.
Midfield is a position of real strength for Marcelo Bielsa's side, with Mateusz Klich's netting three goals in five games and earning an international recall for Poland.
Kalvin Phillips has been a revelation this season, while Leeds also have £4.5 million January signing Adam Forshaw ready to return.
Saville scored 10 goals for Millwall last season and will be a big miss.
Their first game since his departure was a 2-1 home defeat to Swansea, and it will likely be Ryan Tunnicliffe who steps in again.
The former Manchester United prospect has his work cut out against Leeds, who might just be playing Millwall away at the right time.
