Holmes is getting a regular place in the reserves and doing well. Most of the play goes through the left side - Molly and Holmes. He does have the pace and the trickery, but is an old fashioned winger in the mould of Sydenham and Jenkins. He doesn't come inside very often, is more a touchline hugger. AP comes down sometimes. I can only assume he prefers the more flexible approach for the left (and right) side using Lallana. If Holmes gets in, the play would be more cross and head it, and I assume that AP doesn't want to go down that route?!
