ST MIRREN manager Jack Ross believes Lewis Morgan has "everything that he needs" to be a success at Celtic.

The 21-year-old winger's move from the Paisley club to the Scottish champions is expected to be finalised on Friday, after he attended Ross Hall hospital in Glasgow on Thursday for a medical.

Morgan will return to the Ladbrokes Championship leaders on loan for the rest of the season before commencing his Hoops career, and Ross is confident he will make his mark with the treble winners.

"It has allowed us to get to a situation which is ideal with us by having him back for th
