Juventus will take a slender advantage to Portugal after edging past Sporting Club de Portugal 1-0 in the Europa League quarter final on Thursday night.
In a close-fought encounter, which saw the visitors enjoy more possession, more chances and more shots, the first leg was decided with a goal from an unlikely source.
After Sebastian Coates' poor clearance, Juve defender Federico Gatti crashed the ball in with 20 minutes left.
Following a remarkable stoppage-time double save from substitute goalkeeper Mattia Perin, Massimiliano Allegri's men held onto that narrow lead and travel to Lisbon next week for the crucial second leg.
