Spain forward Rodrigo Moreno has warned his teammates they face a tough road ahead as they prepare for Euro 2020 next summer.
The Valencia striker came off the bench to score a dramatic added time equaliser away in Sweden, to secure Spain's place in next summer's cross-continent tournament.
La Roja were wasteful in front of goal in Solna, just as they were in the 1-1 draw in Norway last week, and Moreno knows they need to improve if the 2008 and 2012 winners want to make an impact at the tournament.
"We need to improve, that is very clear.
"If we do not start winning more games, then our abilities will be questioned.
"That criticism would be logical and we must work harder as we prepare for next summer."
Despite taking a pragmatic approach to sealing qualification, Moreno did add that his goal was special and that he was pleased to come on and help the team over the line.
"At times tonight we needed to be more incisive with our play.
"We need to be able to play more direct if we have to.
"We have taken a little longer to qualify, but we are happy, but it is a long road ahead."
Moreno also dismissed suggestions that he is now Spain's undisputed No. 9, after his namesake, manager Robert, left him out of the starting line up against Janne Andersson's side due to a minor injury.
Moreno is set to compete with Mikel Oyarzabal, Alvaro Morata, Gerard Moreno and Paco Alcacer to lead Spain's attack in the coming months.
