Came through a first-half horror against Leeds to really impress after the break as Towler takes on a steep learning curve. | National World
6. Left-back - Connor Ogilvie
Was ugly at times against Dan James, but there are few faster than the winger in English football let alone the Championship. Bounced back on Tuesday and now needs to go again. | National World
7. Central midfield: Marlon Pack
What a performance from the skipper at Leeds and the levels simply have to be maintained to carry his team forward this season. | National World

Some decent moments from the new boy in both games with a blend of silk and steep so far. Photo: Portsmouth FC
