New West Brom loan recruit 'not yet ready', confirms boss

Jimoh-Aloba, also 19, made an instant Baggies debut from the off against Stoke and caught the eye, but Sierra Leone international Mustapha was not in the matchday squad.

Boss Ramsay, whose side tackle Birmingham City at St Andrew's on Tuesday night, said Mustapha is not yet ready to play a role.

"He's not played any senior minutes up until this point," Ramsay said of Mustapha, who spent the first half of the season on loan at Nurnberg in Germany but did not feature.

"So he's not a player that is sort of - on paper - ready to come straight in and contribute.

"Obviously he's a player that has some real qualities. He's done very well for Crystal Palace in the second team and had almost a typical first loan for a lot of players where it doesn't really happen.

"(He was in a) Foreign country, everything that you deal with with that. So I think we will make our assessment as time goes on.

"I think a big part of it for him is being around this environment and some of the tensions that go with it, I'm sure will help."

Albion had to contend with youthful loans with almost no senior experience on deadline day despite a desire to add more nous.

Former Villa loanee Samuel Iling-Junior was recalled and sent elsewhere by Villa chiefs, opening up an opportunity to replace the winger with more experience, but the Baggies could not complete a deal.

With Iling-Junior's exit and Karlan Grant's long-term injury options are more limited to Ramsay and captain Jed Wallace impressed with a first start in more than four months on Saturday against Stoke.

Mikey Johnston had to make do with an impact role from the bench due to a pubis injury and struggled when introduced.
