Thierry Henry has warned Arsene Wenger that he cannot continue his rotation policy for Arsenal's must-win visit of Bayern Munich in the Champions League on Tuesday.
The Gunners host Pep Guardiola's side in a crucial Group F clash knowing that a third straight defeat would deal their chances of reaching the last 16 another blow.
Wenger preferred David Ospina to Petr Cech in the 3-2 defeat by Olympiacos last month, with the Colombian scoring an own goal, and Henry says that his former manager must put his best foot forward.
"One thing for certain is that Arsene cannot rest or rotate any of his star players, as he did when he played David Ospina instead of Petr Cech against Olympiacos," he told The Sun.
"If you don't play your best team against Bayern Munich, you might as well stay at home."
Ospina also started Arsenal's 2-1 defeat at Dinamo Zagreb on matchday one.
