No one is calling Lawlor our new "superstar". That's heaping unnecessary pressure on his young shoulders.
However, to try and answer your question; I think Kellyman will start, fitness permitting. Clubs like Chelsea don't send out their young prospects to merely warm the bench.
Osho will have to be content with a place on the bench - how would you justify rearranging statistically the best defence in the entire football league?
