And in his time at the Fratton helm, Danny Cowley has turned to a large number of players on the pitch.
In fact, there’s been 41 men used by the Blues boss since he succeeded Kenny Jackett.
Of those 33 have played five or more times, giving a reasonable basis to assess their performances with the star and crescent on their chests.

Here’s what we’ve found.

26. Alex Bass - 7.1
Alex Bass just sneaked in after playing seven times for Cowley since his arrival last March. Despite only being limited to a number of outings, he just edged number one Gavin Bazunu and has impressed in the games he’s played. The Pompey academy graduate joined Bradford on loan until the end of the season in January. Photo: Dennis Goodwin
27. Clark Robertson - 7.1
Pompey’s captain has been limited with the amount of games he’s played due to a thigh injury he picked up in September. Despite this, he’s played 12 times in Blue this season and faces a battle with Connor Ogilvie for the final defensive position. Photo: Joe Pepler
28. Hayden Carter - 7.2
The Blackburn loanee has impressed highly since his loan move to Fratton Park in January. Like Walker, he just sneaks onto the least after playing six times since his arrival and has the joint second highest player rating under Cowley. Photo: Portsmouth FC
