A bizarre error meant the wrong Fulham player was substituted during their defeat at Bournemouth - with Marco Silva left raging at the officials after being told the decision cannot be reversed.
Ryan Sessegnon was taken off in the 57th minute of Bournemouth's 1-0 win on Monday but, in remarkable scenes, it quickly emerged that the visitors actually wanted to keep him on the pitch.
An angry Silva furiously protested at fourth official Tim Robinson but his appeals fell on deaf ears owing to Premier League rules.
Regulations state that a player 'cannot return to the field of play during the same match' after being subbed off.
Sessegnon was substituted alongside Sander Berge and Rodigo Muniz as Adama Traore, Raul Jimenez and Tom Cairney were thrown on as part of Silva's attempt to find an equaliser.
However it became apparent that Sessegnon was the wrong player taken off. It is believed Silva instead wanted to remove Sasa Lukic.
'There was a lack of communication with the fourth official from our staff there – the No 2 and No 3,’ said Silva. ‘When I saw Sessegnon out, I tried to correct it. He (Robinson) decided not to let us correct it.’
The farcical incident sparked a five-minute delay and led to referee Michael Oliver coming over to the touchline to see what had happened.
Silva was also incensed at the decision not to send Marcos Senesi off for a challenge on Joachim Andersen in the first half. Oliver gave a yellow card, a decision upheld by VAR Jarred Gillett.
Andoni Iraola immediately replaced Senesi with Illia Zabarnyi, not wanting to risk a second yellow.
'The fourth official was confused throughout the game, in all circumstances,' Silva added.
