Arsenal boss Arsene Wenger believes introducing a quota-based system to the Premier League would be counter-productive.
Rangers boss Stuart McCall says he feels sorry for Gael Bigirimana, but admits he should never have been signed.
Hibernian boss Pat Fenlon claims the club cannot afford to bring former Leith favourite Kevin Thomson back to Easter Road, even if they wanted to.
The Scotland international was released by Middlesbrough on Thursday following an injury-plagued two-and-a-half year spell with the npower Championship side.
That sparked rumours that he could be headed for a return to Edinburgh with his old club.
But Fenlon insists cash restraints simply won't afford him that luxury, although he did joke a act of generosity similar to that shown by former England skipper David Beckham - who signed for Paris St Germain after vowing to hand his salary to a French children's charity - may alter things.
He said: "Kevin's name hasn't cropped up here. With someone like that, and it's similar with some of the other ex-players, as soon as they become available they are linked with Hibs.
"But we are not in a position financially to do anything else. We have done as much as we can - unless he wants to do a Beckham.
"He's a fantastic player and I'm sure he won't be short on offers."
One player who did check in at Easter Road was Barnsley winger Matt Done.
Done was snapped up on a loan deal until the end of the season, with his move confirmed just minutes before Thursday's transfer deadline.
Fenlon will put the player straight into his squad for Sunday's William Hill Scottish Cup fifth-round meeting with Aberdeen and is optimistic that the 24-year-old will make a positive contribution.
He said: "We had identified some players we wanted to look at over the past few weeks and had two or three on the radar for a wee while.
"It was a position we knew we had to fill to give us a different option. I've spoken to people who have been involved with Matt and got some really good reports on his ability and him as a lad, so we were pleased to get him in.
"He can bring a bit of energy to the team, he can also go and play up top which gives us another option. Maybe he can gives us that little spark that we are missing."
The Done deal was the final act of a productive January for the Hibs boss, who also tied down loan recruits Leigh Griffiths, Ryan McGivern and Jorge Claros on longer-term arrangements, while adding twice-capped former Dundee United midfielder Scott Robertson to his squad following a free transfer from Blackpool.
"We are delighted with how the transfer window panned out," added Fenlon. "We said at the start that keeping the three players we had on loan was the priority because of the big part they have played this season for us.
"To then add two quality players is a massive plus for us as well. Scott comes in with experience of the league, while Matt gives us something different."
Hibs could only muster a goalless draw with the Dons in their last meeting, which came just seven days ahead of Sunday's match.
In between those two games, the Edinburgh men also lost out to Ross County with former Hibee Ivan Sproule bagging the winner in Wednesday's narrow win in Dingwall.
Now Fenlon - still bearing the mental scars of last season's humiliating Scottish Cup final defeat to city rivals Hearts - has stressed the importance of a victory on Sunday.
He said: "It's a big game for the supporters, the Scottish Cup means a lot to them. So we want to make sure we put on a performance and get a win."
