Jose Mourinho 'booed a Lazio Under-14s player' and 'told Roma youngsters to feign injury to win derby'

Jose Mourinho has been accused of some serious unsportsmanlike conduct while watching Roma's Under 14 team in the derby against Lazio.

Now in his second season at Roma, Mourinho was shown his third red card of the season in the shock 2-1 defeat to Cremonese on Tuesday after berating the officials just after half-time.

In response, he has threatened legal action against assistant referee Marco Serra, claiming he told him "mind your own f***ng business' and to "go home" as things got tasty on the touchline.

Mourinho demanded an audio recording of their exchange, where he claims he was spoken to "in the most inexcusable way"

But the Portuguese manager has been dragged into further controversy over his alleged behaviour at an academy game.

Mourinho was in attendance for the mini Derby Della Capitale on Sunday and according to Il Messaggero, via Get Football News Italy, he booed Lazio youngster Alexandru Milou from behind the Roma bench as he stepped up to take a penalty in attempt to put him off.

Footage doing the rounds on social media show that there were indeed loud jeers as Milou prepared to take the spot-kick, although there's not a video of Mourinho.

In addition, the 60-year-old is reported to have told his players to 'feign injury and time-wasting' - which sounds like the type "sh**housery" he's used during his time at Chelsea, Real Madrid and Inter Milan - when the Giallorossi found themselves 2-1 up.

Lazio are believed to be furious with Mourinho's antics, with Lazio's Under-14s coach Tobia Assumma reportedly saying,

“No, mister. This is not done.”

After the win, Mourinho was seen celebrating with Roma's youngsters, many of which did the '2-1' scoreline gesture with their hands.

He then invited them into the gym to meet the first-team squad and take pictures.

For the loss to Cremonese, Mourinho had to watch the second half from the stands along with assistant Salvatore Foti, who was handed a one month touchline ban for his behaviour against the same side in the Coppa Italia.

The FIGC Prosecutor’s Office has reportedly opened an investigation.
