Jose Mourinho kept his Roma players on the pitch for a full-time team talk after their 3-2 defeat against Lazio in Sunday's Derby della Capitale.
The Giallorossi suffered their second Serie A defeat of the season against Maurizio Sarri's men, who stormed into a 2-0 lead in after 20 minutes at the Stadio Olimpico thanks to goals from Sergej Milinkovic-Savic and Pedro.
Ibanez pulled one back for Roma four minutes before half-time, but just under 20 minutes into the second half Felipe Anderson restored Lazio's two-goal advantage.
Jordan Veretout fired in a penalty six minutes later to give Mourinho's side a glimmer of hope, but they were unable to find an all-important equaliser against their bitter rivals.
Roma have now lost two of their last three league matches, having also slumped to a 3-0 defeat away at Verona last weekend.
And after watching his side come unstuck again, Mourinho decided to conduct his full-time team talk on the pitch at the Stadio Olimpico.
The 58-year-old refused to disclose what he said to his players, insisting it stays between them.
“What we said stays between us. I wanted to immediately do the talk there, but with the same intimacy as the locker room," he told.
“Let me say something positive first, which is that Italian football has improved a great deal from 10 years ago. The quality of football, the attacking approach, the desire to win, has all improved.”
Mourinho was left furious with a number of refereeing decisions in the derby, claiming Lucas Leiva should have been brandished a second yellow card for an elbow.
