Jose Mourinho has been accused of unsporting behaviour by the coach of Lazio's Under-14 team after the Roma boss allegedly booed one of his players.
Mourinho is claimed to have booed Lazio teenager Alexandru Milou while he was taking a penalty and is alleged to have encouraged his Roma players to waste time during the match, in order to upset their opponents.
The latest episode of drama comes in the same week Mourinho was sent off for the third time this season during the professional team's shock defeat by Cremonese, which was their first Serie A win of the campaign.
