This all the way. Get the players in now (and a new manager soon) who can keep us up this season. The summer is a better time to make permanent signings (theoretically at least).
I'd be happy to see O'Brien and Wright sign as O'Brien has been clearly better than any midfield option we have other than Franco, while Wright is hopefully a promising talent. It did concern me that both seem to be more defensive midfield options when we also need someone more attacking/creative. Clark could be that player and although I don't think we are going to get him in on loan, I did see in that BBC article that the manger who signed him for Salzburg left in December. If his replacement doesn't rate him and is happy to get his wages off the books until the end of the season, perhaps this could have legs?
It's the hope that kills you, etc.
