Martin Odegaard believes Arsenal's failure to win the Premier League last season will haunt him for as long as he lives.
Mikel Arteta's side topped the table for the majority of the campaign and looked set to end their 19-year wait for the title.
But the team imploded in the final weeks of the season as they won just three of their last nine games, allowing Manchester City to overtake them and claim their third successive title.
Odegaard is yet to put his finger on exactly what went wrong, and has admitted it has been tough to come to terms with his side's collapse.
