Tottenham boss Andre Villas-Boas was left frustrated missing out on Champions League qualification.
Despite his troubles, the 35-year-old ended the season with 72 points - more than Spurs have ever accumulated since the Premier League began.
"It's very, very unusual that we didn't make it," the former Chelsea manager said.
"If you look at past seasons with that number of points you would normally achieve it.
"It's difficult for me. Obviously we would ideally have achieved that fourth spot, we certainly did enough to deserve it, but we didn't in the end."
