Clarke said his players performance in these two Test matches have been unacceptable and was nowhere near the standard set out by an Australian cricket team.
"I think in the first two Test matches, we've let each other down. That's the most disappointing thing for me. At stages, we've got out to let our partner down. We've bowled bad overs which let's your bowling partner down as well. We've dropped catches to let the bowlers down. As a team, we're letting each other down and that's the most disappointing thing," he said.
