Manchester United has cautioned Manchester City fans that they will be ejected if found in the home end at Old Trafford for the Carabao Cup semi-final.

The two clubs jointly decided to cut away allocations for the two-legged match, with the first game being played tonight (Tuesday), due to security reasons.

Man United said that any supporters “visibly or audibly” supporting the away team in the home areas will be denied entry or removed from the game.

Fears over Man City fans buying tickets from the home fans escalated after Man United failed to sell out and opened the tickets up to general sale.

Man United said in a statement: “We have a series of measures in place to minimise any risks and anyone visibly or audibly supporting the away team in home areas will be denied entry to the ground or ejected during the game.”

The home team also emailed their season ticket holders with a reminder that “all tickets must be used by Manchester United supporters”.

Man City has received an allocation of 3,000 tickets for tonight’s game, with Man United getting around 2,800 for the return leg at Etihad Stadium on 29 January. These figures were decided upon by the clubs instead of the usual 10 per cent allocation due to several incidents that involved racial abuse of a player during last month’s derby.
