West Ham’s Lucas Paquetá is just one booking away from suspension, having already picked up four yellow cards earlier this season.
The Brazilian was cautioned in matches against Aston Villa, Tottenham Hotspur, Manchester United, and during the ill-tempered 3-0 defeat to Nottingham Forest in the Premier League.
Another yellow card would see Paquetá hit the five-booking threshold, forcing him to miss a game.
The Hammers have struggled with disciplinary issues this season, leading to a string of cards and suspensions. Winger Mohammed Kudus is currently serving a five-game ban for a confrontation against Spurs players, amid reports he also had to be separated from head coach Julen Lopetegui during a heated half-time exchange.
Edson Álvarez has also been sidelined, missing West Ham’s clash with Everton after a reckless red card in the match against Forest.
Paquetá now faces a tricky balancing act, with Kudus still unavailable until the increasingly critical Premier League fixture against Leicester.
