James Morrison believes West Brom paid the penalty for lacking players with top-flight experience after their relegation from the Barclays Premier League.
The Scotland international, who missed the conclusion of the campaign with a heel problem, feels by the time Albion got used to playing against the elite it was too late to salvage their season.
Morrison said: "The lads now know how to win games in the Premier League, but we ran out of matches. The lack of top-flight experience in our squad has been one of the main factors of the season."
He added: "It took time for the lads to get used to that level of football and, in the second half of the season, we started getting a grip of it.
"There are a lot of pluses despite relegation but it will be difficult because there is a lot of pressure on us to get straight back up.
"At least we'll go into next season with the experience of getting promoted from the Championship before.
"Maybe a few more faces, who are used to the Championship, can help us and we'll hopefully get straight back up."
