Lazio lost 2-1 to Juventus, but Reja managed to take home some positives from the game.
“[Luis] Cavanda is a young player, and should not given that much space to Krasic in the end,” Reja told Sky Sport.
“His inexperience meant we paid the ultimate price.
“It is disappointing because the match was already over, but we couldn’t hold on. In the end, we didn’t have enough of the ball. There is a lot of disappointment as we lost with five seconds to go.
“Now, it becomes difficult to keep our spirits up, but we did demonstrate that we could take it up to Juventus.”
