For a club who have been tugging at the financial purse strings for the last few years, someone is doing something right at Rangers.

This week's £7.8million sale of Carlos Cuellar represents some more top business by the Glasgee outfit, most notably because they picked up the player only a year ago from Osasuna for less than a third of that amount.

Forget the need to cut their cloth following the disastrous European exit to FBK Kaunas, the transfer represents good old-fashioned cultivate-and-flog economics, the like of which would have John Maynard Keynes dribbling all over his abacus.

The only problem I have with these type of transfers are as follows: Accepting that player loyalty doesn't really come into it, as loyal or not, the club will snatch the cash without the need for a second invitation, Martin O'Neill must surely be asking questions of his scouting network as to why Cuellar hadn't been sounded out before now?

It's a bit like all the fuss over Russian looker Andrei Arshavin - the guy's 27, and if he was really as good as his Euro 2008 performances suggest, shouldn't he have at least been touted for a move onto these fair shores at some point over the past decade, rather than on the basis of scoring against Sweden?

But the biggest concern I would raise concerns the past evidence of Rangers picking someone up then flogging him to the Premier League less than a year later for a princely sum.
