The 19-year old striker was mostly used as a substitute during his last five-month tenure on-loan last season. But the Swans boss is impressed with the England Under-19 international and has no doubts about his abilities.
"Febian settled in straight away when he came to us," he told Swansea's official website. "He loved every second of his time here and you could see him improving every day."
"He was slowly fulfilling the Premier League potential he has and now we are waiting for the go-ahead to sign him on a season-long loan. I have spoken to Febian about it and I know he is very keen to come back."
