West Brom midfielder James Morrison believes the contribution of Romelu Lukaku has been central to the team's impressive form this season.
Lukaku scored his 13th goal of the campaign during Saturday's 2-1 victory over Swansea to keep alive Albion's hopes of securing a European spot.
And Morrison insists Albion should pull out all the stops to try and get the on-loan Chelsea striker back at The Hawthorns next term.
Morrison knows the 19-year-old will leave a big hole to fill should he be recalled by the Blues next season.
Morrison said: "Romelu's goals are one of the reasons we are where we are. Hopefully the club can get the deal sorted. He is a pleasure to have and I think he will be even better next season.
"Will he benefit from another season at West Brom? Definitely. You think how young he is for such a big unit.
"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.
"He is big and strong and scores goals and is quick and powerful. He is a handful for anyone."
Morrison also believes Albion will need to strengthen their squad if they qualify for Europe.
He said: "We will need some players in if we are going to (play in Europe).
"You saw what we were like in December and January when we couldn't pick a win up (through players missing).
"Probably the manager will realise that and hopefully we can get there and build a squad for it."
