Lazio boss Simone Inzaghi was left frustrated after their 3-2 defeat to Inter Milan.
Inzaghi believes they blew their Champions League chances earlier this season.
“We probably should've sealed the Champions League place earlier in the season," he told Mediaset Premium.
“We had a great journey, this evening with the game in hand, we conceded three goals from set plays. Maybe it was our destiny that Lazio wouldn't enter the Champions League.
“There is regret, but this result does not change the overall season my lads had, as they have been extraordinary from the Italian Super Cup victory onwards.
“This disappointment will remain with us for a long time, but we'll have the summer to meditate over it. We had our chances to finish it, we dominated the game and Inter scored three goals without Thomas Strakosha ever really needing to make a save.
“We are the most prolific team in Serie A this season, we were unbeaten in 11 rounds, but all that was not enough. Perhaps we're not mature enough yet, as towards the end of games we tend to lose our way."
