Rangers needed Eduardo Herrera to start justifying his £1.5 million price tag when he came off the bench to replace the injured Alfredo Morelos midway through the away clash with bottom of the table Dundee on Friday night.
But, 45 minutes later, Rangers were mourning a second successive defeat as two goals from Mark O’Hara condemned Graeme Murty’s side to a 2-1 loss. And Herrera, who has scored just once in 11 Scottish Premiership games since arriving from Liga MX side Pumas UNAM, was once again ineffective in attack.
In fact, Herrera is perhaps the biggest disappointment of a summer transfer window in which Rangers spent almost £10 million on a raft of new players – almost all of whom have struggled to live up to either their reputation - or their price tag.
And, just to make matters worse, Herrera has been comfortably outperformed in 2017/18 by two players who left Ibrox in the summer to make way for his arrival.
Ipswich Town signed both Martyn Waghorn and Joe Garner from Rangers for a combined fee similar to that which the Glasgow giants paid to bring Herrera to Scotland.
Garner might have netted just five times in 17 Championship games for The Tractor Boys, but his work-rate and ability to lead the line has made him absolutely indispensable for Mick McCarthy’s side. And Waghorn, who was often the subject of criticism from Rangers supporters last season, has nine goals in 13 league starts.
The Daily Record reported after Pedro Caixinha was sacked in October that Herrera, who worked with him at Santos Laguna in 2013/14, is facing an uncertain future at Ibrox. And with no sign of improvement in his form, perhaps the best thing Rangers can do is to cash in on the striker before his value drops any further.
