The 18-year-old scored a hat-trick in the 3-2 win against Middlesbrough on Monday and his sparkling performance promoted a positive response from Beale.
Beale said: "We know with Sheyi that he's a fantastic physical specimen.
"We want to see him running and breaking lines. We want to see him play with his foot to the floor from the first whistle. Sheyi responded really well.
"It was an important game for us and we were the better team throughout."
