Osman Sow is one of the more obvious transfer targets Rangers could be looking at. Of all the players in the SPFL out of contract at the end of the season, he's by far the standout.
According to the Edinburgh Evening News, Rangers are indeed looking at him. As are Celtic and Birmingham City. They report that Sow hasn't reached a decision on his future yet and might even stay at Hearts, being perfectly happy to finish the season there.
We're a bit indifferent towards this one - he's a good player, and wouldn't cost anything, and it's very hard to find reliable goalscorers at any time of year. We could probably do with another striker, and Sow isn't a million miles away from the alternative, penalty-box physical goalscorer that many of us want to see.
On the other hand, his goalscoring record is hardly outstanding, and he can be a bit erratic with his decision-making when running with the ball, which might make it difficult to fit him into our system. He doesn't really seem like the sort of player Mr Warburton would go for, from what we've seen.
Regardless, Sow will probably weigh his options up for a while longer before coming to any decision. It's an interesting one to keep an eye on, however.
