Arsenal captain Cesc Fabregas admits he wasn't at his best this season.
"When I look back at the season personally, I must say that it's been difficult," he said.
"From the start of the campaign I didn't have the perfect pre-season because I was involved in the European Championships until the final. I know I didn't play well this year; I feel like I didn't improve. Next year I will come back stronger and I will do better."
