The 19-year old Belgian striker, on a season-long loan from Chelsea, has scored 12 Premier League goals this campaign and teammate Morrison feels he would be open to another spell at The Hawthorns as he continues his ascent into a top-line striker.
"Will he benefit from another season at West Brom? Definitely. You think how young he is for such a big unit," Morrison told reporters.
"He is a pleasure to have and I think he will be even better next season.
"He's got a lot of hard work to go but I'm sure he is going to be a top player. I'm sure Chelsea are going to develop him."
Morrison added: "Romelu's goals are one of the reasons we are where we are. Hopefully the club can get the deal sorted [for next season].
"He is big and strong and scores goals and is quick and powerful. He is a handful for anyone."
