With the question of playing both Grimes and Fulton does the new manager need to carry on with the system he wants to play trying different player or take look back at when these were most effective under past managers
If he looked back, Duff would see that them playing in front of a back four resulted in a defensive strengthing of the team while with the right midfield and forwards around them we could get forward effectively.
You could say under Cooper we didn't score enough but you must remember at times we had Hourihane and Cory Smith the latter being a more workman but little composure once he got anywhere within sight of goal, Hourihane disappeared at time.
Russell at times when seemingly force into a back four had good runs of games.
But as stated with Coopers team it depended on the players picked around them, think we have the players now around them after new younger more mobile players being introduced, still waiting on the left side to be sorted but as we saw with Martin even one of the most derided players Lati fitted into a winning back four.
Only a of word of caution is age, is Fulton's able to do the legwork he did in the past, he needs help and has had to be replaced in games. Grimes also while not the fastest around the park looks off the pace again needs help.
The natural choice was Downes, sold, now Allen but too injury prone. Ollie in a more withdrawn role to help out? Key who may be looking for a position if the left footed play is sorted
Eventually Grimes and Fulton will need replacing especially if continued to be used in a team with a 3 man defence set up.
