This article forms part of our Profit Players feature series, which is where Football Transfer Tavern takes a look at how well a player has fared since being signed or sold, using statistical figures and statements from pundits to prove how good of a deal the club managed to achieve.
Back in January 2010, Celtic picked up midfielder Sung-yueng Ki from FC Seoul for £2.16 million, per Transfermarkt. The South Korean would enjoy two and a half seasons at the club and clearly performed well as he ended up moving to the Premier League after his spell at the Hoops.
Whilst at the Scottish side, Ki managed to make 87 appearances in all competitions including the Champions League, scoring 11 goals and picking up 15 assists, per Transfermarkt. The amount of appearances he stacked up in such a short time highlighted that he was a key player to the squad in Neil Lennon’s first spell in charge.
Whilst at the club, he won the Scottish Premiership once as well as the Scottish Cup once, a decent trophy haul given he wasn’t in Glasgow for that long.
That Premiership title he won in 2011/12 was huge for the club as it was the start of their dominance in the country, which has seen them win nine league titles in a row from that season to the one just finished. They will now look to win 10 in a row and if they do it, Ki would be a big part of that history having been instrumental in the first title of the streak.
His performances at the club did not go unnoticed as he was picked up by Swansea City who were in the Premier League at the time. They paid £6.30 million for him, so not only did Celtic get the best out of him as he was an integral part to their side, they also made £4.14 million on the player, which emphasises that he was a very good profit player for the Bhoys.
After this his next moves to sides like RCD Mallorca and Newcastle were free transfers, which further highlights how good a deal it was for Celtic as they managed to sell him at his peak value.
Hoops fans, how good was Ki when he was at the club? Comment below!
