The players/teams that are best suited to this would be teams with young players with good work rate, teamwork, determination.
Lampard's Chelsea play gegenpress which requires a lot of energy, energy mainly from his young players.
In terms of training & opposition instructions I leave that to my assistant manager or my best coach.
1-0 down? Change the mentality to Attacking and tell them to push forward.
I never change any player instructions, team instructions or roles in game. I leave the tactic the way it is.
