It is difficult to imagine Jose Mourinho worrying about the value for money he elicits from a loan signing, but then the Chelsea manager doesn't seem to share the same financial constraints as his Walsall counterpart.
Paul Merson needs to squeeze every last drop of value from his deals and it is why he is particularly pleased with Erik Skora, the midfielder whom he has managed to retain for an extra month.
The Saddlers boss hopes Preston North End will even allow Skora to play in the FA Cup second-round match against Yeovil Town at Bescot Stadium on December 3.
Skora's loan spell has already reaped rich rewards. The 24-year-old striker has score three goals since joining Walsall, twice in League One against Gillingham and Milton Keynes and the third to advance Saddlers' cause in the LDV Vans Trophy against Bournemouth on Tuesday night.
That is definite value for money and Merson hopes it will only appreciate before Skora's time is up on January 14.
"They are letting us keep him for an extra month, so that is good news," Merson said. "We have him for the whole of Christmas, which is a lot of games. It is a lot of value.
There appears every chance that Skora will also be allowed to play in the FA Cup for the Saddlers.
"He is a quality player with quality feet," Merson said. "We have a very heavy programme, especially now with the LDV,
which is why Eric is a good signing. When you look at loan deals you have to look at the value you're getting and how many games they can play.This is a lot of games."
Merson has been further bolstered by the probable return of midfield player Simon Osborn although Chris Westwood, replaced in defence on Tuesday by Steve Staunton, has a slight hamstring problem and is unlikely to play.
Osborn, along with Mark Kinsella, are the keys to the Walsall midfield. Kinsella may need more rest after suffering a knock two weeks ago and Merson would prefer not to put the former Aston Villa player under undue pressure to return. Osborn could do his team-mate a favour if fit.
Merson said: "As long as he [Osborn] doesn't do anything wrong in training, he will be fit. He will be straight back in because I haven't got another midfield player. He has been our best player this season.
"Mark is touch and go, I think. He loves his football. We have to hold him back because [otherwise] he will rush back and set himself back three or four weeks."
