Just something I spotted on the Official FA Rules page...
the occupants of the technical area:
are identified before the start of the match in accordance with the competition rules
must behave in a responsible manner
must remain within its confines except in special circumstances, e.g. a physiotherapist/doctor entering the field of play, with the referee’s permission, to assess an injured player
only one person at a time is authorised to convey tactical instructions from the technical area

Note the bottom line (underlined).
Something to watch out for in future, when opponents' manager, physio and substitutes all jump up shouting at the linesmen or referee!
