Ronald Koeman has resigned as coach of Dutch champions Ajax following their elimination from the Uefa Cup.
Koeman said he no longer had the energy
Two second-half goals from Auxerre led to a 3-1 defeat for Ajax on Thursday - and the former Holland defender decided to quit following a meeting on Friday.
"Last night's result was decisive," said Koeman, whose contract was due to expire in July 2006.
"I don't have the strength or the energy to bounce back and make this team work more effectively."
