Chelsea will reportedly warn their supporters over behaviour ahead of tonight's League Cup fourth-round tie against Manchester United.
The two sides go head to head just days after United's explosive 3-2 win over the Blues at Stamford Bridge on Sunday.
Following the weekend's fixture, a steward had to be taken to hospital with a knee injury after a crowd surge in the Matthew Harding stand following Javier Hernandez's winning goal for the Red Devils.
The Blues will remind supporters of their responsibilities in the match programme this evening and security will reportedly be increased.
