Highly rated French manager Paul Le Guen, who had led Lyon to three consecutive Ligue 1 titles was the man tasked with reclaiming back the league title from rivals Celtic, and as one of the most sought-after coaches on the continent, it looked like Rangers would go on to dominate.
His spell turned into a nightmare and he lasted just 6 months, quitting in January 2007, but not before making one of the worst signings in their recent history.
If the Frenchman thought he was getting a talented striker who could light up Scottish football, then he was sorely mistaken.
Sebo opened his account against Hibernian in a 2-1 defeat and added a late winner against Aberdeen two matches later, but that was to be it for the Slovakian at Rangers, playing a further 22 matches without adding to his tally.
Despite scoring against Chelsea in a pre-season friendly ahead of the 2007/2008 campaign, Sebo was soon on his way out of Ibrox for a loan spell with Valenciennes before joining permanently in 2008 for a fee of £750k, with the club losing just over £1m on the player.
The striker cost the club £900k per goal and this wasn’t money they had to throw away. The player was even dubbed “misfiring” by BBC Scotland and this shows just how bad he was at the club.
The Light Blues returned to the summit of Scottish football under Walter Smith following Le Guen’s reign, however, the mere mention of Sebo’s name will send shivers down the spines of many Rangers supporters.
