Stoke City striker Saido Berahino appeared to have got his days mixed up, as he arrived at the training ground on Sunday in his matchday tracksuit ready to play Manchester United.
The 24-year-old was mocked by team-mates Kurt Zouma and Eric Maxim Choupo-Moting on Instagram for seemingly presuming the clash at Old Trafford was on Sunday instead of Monday night, live on Sky Sports Premier League.
Zouma uploaded the story onto social media, poking fun at Berahino, who was wearing a full Stoke tracksuit and holding a washbag apparently ready to board the coach to Manchester.
Berahino, who joined the Potters in a £15m deal from West Brom a year ago, did not confirm or deny if he had made the mistake - much to his team-mates' amusement.
Stoke were training on Sunday before heading to Old Trafford on Monday without a permanent manager.
Coach Eddie Niedzwiecki will be in caretaker charge against United as Stoke's search for a new manager continues, after former Watford boss Quique Sanchez Flores pledged his commitment to Espanyol.
