West Ham United welcome Liverpool to the London Stadium on Monday night.
But it seems as though Manuel Pellegrini may have got his teams confused, with his programme notes instead claiming Arsenal are Monday night’s opponents.
Someone on the programme editing team for the Hammers appears to have accidentally re-printed the exact same programme notes from when the Gunners visited east London in January.
The home side will be hoping they can get a repeat performance as they won 1-0 against Unai Emery’s side.
Manuel Pellegrini named a side without Marko Arnautovic in the squad after his injury against Wolverhampton Wanderers.
For the Reds, James Milner came in at right-back, with Adam Lallana replacing the injured Georginio Wijnaldum.
