The pair have each spent time on Celtic’s books this decade.

Two former Celtic employees could soon become colleagues in Norway.
According to the Scottish Sun, the one-time Bhoys boss, Ronny Deila, has offered a three-week trial to the club’s old right-back, Efrain Juarez, at Valerenga.
The pair’s paths never did cross at Celtic, with Juarez having been gone two years by the time of Deila’s 2014 arrival at Parkhead.
But in quotes published by the Scottish Sun, the Norwegian explained: “Efrain arrives with a very good pedigree. I know about him through my contacts.
“His wife is from Belgium and he wants to try European football again.”

Celtic are reported to have paid £4 million to sign Juarez from Pumas UNAM in July 2010.
But the Mexico international only played 20 times for the Bhoys, who loaned him to Real Zaragoza a year later, before selling him to Club America 12 months the following June.
He later moved to Monterrey, before signing for Vancouver Whitecaps in January 2018.

But he is currently without a club after the Canadians released him at the end of last season.
Whose Celtic spell was worse – that of Juarez or Deila?
