Ostemobor scored Crewe's second equaliser in their 2-2 draw with Leicester last night, earning the praise of manager Dario Gradi.
"To come back twice was a great achivement," said Gradi.
"Jon had an impressive game and I'm glad he scored. I had a bit of a go at him after the last game. But he responded well and if he carries on like that he will be a terrific player."
