He arrived amid great expectations but left barely noticed after the ultimate roller-coaster Celtic career.
Getting a £2m Mexican internationalist straight from the World Cup seemed an incredible deal and the first indication of a real far reaching scouting network getting involved away from the usual markets.
The first signs were awesome. An all action midfielder with an eye for goals.
When Celtic played in the pre-season Emirates Cup at Arsenal there were fears that the great secret might be out the bag with bigger spending English clubs alerted.
Yes he was that good and then came an international break which made the wrong type of headlines.
With goals scored against Braga and Utrecht Juarez went off on international duty and returned with a six match international ban after lurid tales of prostitutes and a transvestite.
At the same time Beram Kayal was starting to emerge, a player very much in the image of Juarez without the same goal touch.
After that international break Juarez started to drift out of the Celtic side, he made seven more appearances before new year then was used even more sparingly in the second half of the season, missing out entirely on the Scottish Cup Final win over Motherwell.
The 2011/12 season started with a 6-0 defeat from Real Madrid while on loan at Real Zaragoza, on 7th January he made his last appearance in La Liga before being returned to Celtic.
At the end of the season, halfway through his Celtic contract he returned to Mexico, joining America for an undisclosed fee.
Juarez was quickly on the move to Monterrey where he seems to have settled down and is now in his fourth season with the club.
At the age of 28 it seems that he has settled for life in the Mexican league after the disappointments of a spell as a junior at Barcelona and 19 appearances for Celtic.
