The classy and elegant playmaker arrived at Celtic Park for a fee thought to be just over £2 million back in January 2009, and went on to be a successful signing after an initial rocky patch at the club.
After winning the Scottish Cup in 2011 and the Scottish Premiership in 2012, Ki was sold on to Swansea City in 2012 for almost three times what Celtic paid for him three years earlier.
Ki has been held up as an example of the Hoops’ clever and prudent signing policy but it turns out the current Rangers boss had a big say in the 28-year-old’s move to Glasgow.
Speaking via the Daily Mirror, the Portuguese coach explained: “I was in Glasgow for my UEFA Pro Licence and I met Helena Costa, who was already working for Celtic.
“I spoke to her about Celtic setting up a base in the Iberian Peninsula and even recommended a player to them – Ki Sung-yueng, which they signed and is now at Swansea City.”
So, there you have it – Pedro Caixinha played a pretty vital role in at least one Celtic signing.
But what do you think of his anecdote?
