Juventus are out of the Champions League, and deservedly so, on balance. You can break down the episodes from both legs of their last-16 game with a fine-tooth comb and tell yourself this could have ended differently: they gifted Porto two goals in the first leg, they hit the woodwork twice on Tuesday and maybe, if Alvaro Morata, Adrien Rabiot and Cristiano Ronaldo had shown a little more concentration and bravery on Sergio Oliveira's free kick in extra-time, you wouldn't be reading this column (at least not in March). Instead, all three jumped and turned at the same time, allowing the ball to sneak under the wall and into Wojciech Szczesny's far corner.
