Vicente del Bosque has offered support to Jose Mourinho in the wake of his touchline row with Chelsea's Antonio Conte.
The former Spain and Real Madrid boss says he can understand the Manchester United manager's frustration, having had a similar experience with the spirited Italian.
Mourinho's men were on the receiving end of a 4-0 demolition at Stamford Bridge on Sunday and the Portuguese took particular exception to Conte's animated celebrations after N'Golo Kante's fourth goal.
Mourinho felt his counterpart had gone over the top and made his feelings clear at the full-time whistle.
