...although the Pilgrims have put themselves in a good position to attract loan signings.
Argyle's current list of loan signings stands at five; Craig Tanner from Reading, Oscar Threlkeld from Bolton, Hiram Boateng from Crystal Palace, and the two new loan signings Luke Croll, also from Palace, and goalkeeper Christian Walton from Brighton.
Derek thinks that the way in which Argyle have treated their loan signings means that clubs will be more willing to let their players join the Pilgrims on loan, as they know they are being well looked after at Home Park.
"The players do not need persuading," said Derek, "but the clubs just have to look at their own situation. It's never easy getting players in but the clubs we have dealt with have all been very helpful towards us.
"I think when you look after the players we have had from Reading, Bolton, Palace and Brighton now, if you look after them then you have always got the opportunity of going back and getting another player because the player likes it and the club knows you are dealing well with them so it gives you the opportunity to get the better players from those teams."
Derek continued to explain that the board had been helpful last week as he looked to bring in reinforcements.
"They knew how tight the squad was that we were working with and knowing the board, they are very supportive of the football club," said Derek.
With five loan signings at Home Park already Derek has said there is a slim chance of any new additions before Wednesday.
"I would find it highly unlikely, but you never know. We have got five loan signings; it is probably more than I would want. We have got that at this moment in time, but we will still look and see."
With Hiram Boateng, Carl McHugh, Luke McCormick, Reuben Reid, Peter Hartley all away from first team action, Derek has said that they are all heading in the right direction.
"They are progressing well. We are always hopeful, we are looking on a daily basis so we haven't ruled anything out yet."
