Lamouchi, 54, was dismissed by mutual agreement following Sweden's dominance in Sunday's Group F match at Estadio Monterrey in Guadalupe, Mexico. The Frenchman, appointed only in January after Sami Trabelsi's Africa Cup of Nations exit, managed just one win in five games in charge.
Herve Renard, former manager of Morocco and Saudi Arabia, takes temporary control of Tunisia for the remainder of the tournament. The move marks an extraordinary managerial upheaval during World Cup group play, unprecedented in the competition's history.
Tunisia's opening warm-up fixtures saw defeats of 1-0 to Austria and 5-0 to Belgium, signalling pre-tournament struggles that culminated in Sunday's heavy loss.
Tunisia face Japan (21 June) and the Netherlands (26 June) in their remaining Group F fixtures. Managerial instability during the group stage may destabilize team cohesion; their depleted squad now faces stronger opponents with an interim coach, affecting betting markets on their progression odds.
