Newcastle boss Eddie Howe admits no-one expected Champions League football at the start of the season.
Howe has declared they've overachieved this term.
"It's not something at the start of season we could have predicted," said Howe. "It is a tough league. The challenge we face is at the highest level and we have had to be very consistent. That is the biggest compliment I can pay the players.
"To do this achievement is not something taken lightly by me. It's a massive moment for us. Living up to that expectation is going to be the hardest challenge.
"We have overachieved and will have to keep overachieving. To match the expectations is going to be our biggest challenge."
He also said: "We have to keep the majority of the squad together, they have earned the right to do that but we also have to be good in the transfer market.
"I am feeling good. It's been a hectic few days. You get on planning for next season straight away.
"The players will be leaving for their summer break after Sunday's game, so there is a lot of work going on behind the scenes."
He added: "It is an incredible achievement. I am so pleased to be able to get it done in front of our supporters. The scenes after the match are something I will always remember."
