What pushed Jokanovic over the edge on Saturday was the computer-says-no verdict of Kline’s data model when it came to Pereira. It was not even that Pereira failed the test. It was simply that despite his reference from Mourinho, Kline said Pereira could not even be considered because he simply did not have enough data – minutes played - that could be submitted for analysis.

In February, Kline was sent back to the United States while the original fuss around him died down but it was always the intention of Tony Khan that his friend would return. Kline duly came back and while Jokanovic will be in charge of the team for tonight’s EFL Cup tie against Middlesbrough, his skewering of Kline after the weekend draw with Cardiff means the future is uncertain, to say the least.

In reality, it seems that Kline never really went away. He worked remotely towards the end of last season and he is not the kind of man who keeps normal office hours anyway with emails about statistical analyses as likely to drop into the inboxes of staff at Fulham at 3am as 3pm.
