The Saddlers, as with many clubs both in the lower reaches of the EFL and throughout non-league will have a much-reduced budget for 2020/21 and will have to 'make do and mend' with both the loan market and their youth academies likely to be their biggest source of players.
Clarke, who is set to release just five permanent members of his squad at the end of the month, believes the club were able to help last season's group of loan players improve, with the likes of Rory Holden eventually forcing his way into the starting line-up.
42-year-old Clarke went on to admit he would happily welcome back many of last season's loanees, before admitting its not down to him with many other factors in play before any players could make a potential return to WS1.
Speaking to the Express & Star's Walsall correspondent Liam Keen, Darrell said; "Improving the team is going to be difficult with the financial implications that have gone with us finishing the season and no revenue coming into the club.
"As things stand, unless things change, it will potentially only be loans coming into the club. Rory is a player that I really like, he grew into his role.
"The loan players that we had last year were exceptional, with the lads and their attitude – exactly the sort of type of loan players that we needed to bring in. Not only did their performances improve, they were the right people to have in the environment and the changing room.
"We’ll see what the window brings and they’re players we’d like to bring back, because they did well, but they’re at their parents clubs. It’s one of those, they’re not our players, so we’ll see."
