Glasgow Rangers have endured their fair share of transfer howlers over the years in signings that have turned out to be flops and players they allowed to leave who went on to do great things.
However, there have been plenty of times where the Gers have wanted to bring a player to Ibrox during a transfer window and either avoided a blunder or missed out on a gem.
One player the club missed out on was John Hartson in the summer of 2000. They agreed a £6.5m deal to sign him from Wimbledon before he failed a medical and eventually ended up at rivals Celtic, where he went on to score 110 goals in all competitions, and in the words of the Welshman himself – “ruined Rangers” – on his own.
The now-retired forward recently revealed that he had a second opportunity to sign for the Gers after his time on the other side of Glasgow, saying: “For me personally, I had a chance to go to Rangers after Celtic. Sir David Murray called me up and said ‘we would like to sign you now, the medical is gone and you have had your time at Celtic’.
“I was at West Brom. I don’t think I would have ever been accepted at Rangers because of my success at Celtic. The 110 goals I got for Celtic I felt I might as well go and chuck them down a river, because I would never be forgiven.
“It’s a huge rivalry. I’m not knocking anybody, but for me it’s like all my family grew up as Swansea supporters. I just couldn’t sign for Cardiff.”
Instead, he opted to sign for English side Norwich City in the summer of 2007 instead of making the unforgivable move to the other Old Firm team.
The attacker, who scored 172 club career goals, spent five years at Celtic and clearly felt like he would not have been welcomed by the Light Blues supporters.
It is impossible to say for sure but his form at West Brom suggests that he would not have done enough on the pitch to win over the fans at Ibrox. He scored five goals in 21 Championship matches in the 2006/07 campaign for the Baggies after leaving Glasgow and then failed to score in four matches on loan to Norwich before he retired.
His lack of production in England came off the back of him scoring 18 goals in 26 league matches for Celtic in his final season in Scotland, as he struggled to recapture his predatory instincts south of the border.
The striker was at the end of his career and his record for West Brom and Norwich indicates that he did not have the same goalscoring prowess that he had in his pomp at Celtic, which is why signing him would have been an error by Murray as he would not have performed well enough on the pitch to make up for his exploits at the other Old Firm club.
