The 21-year-old scored 8 goals in 42 league appearances while on loan from Newcastle, and Taylor was impressed with his efforts.
"He had a great season with Blackpool and it shows in the way he plays. He's got an eye for goal and he scored a couple of screamers last season," Taylor said in an exclusive interview with TribalFootball.com.
"He's training and playing with quality players, he's getting some great experience and he shows his class. Hopefully he keeps it up and he'll break into the squad soon."
Taylor's comments come at a time when the FA are looking to cut down the foreign player quota in order to promote the development of homegrown players and help deal with issues arising from Brexit.

Both associations were investigating whether Longstaff qualified for either country.
However, the Newcastle native does not have any family connections with either country and only qualifies for England at international level.
