For a player whose confidence and form in front of goal fluctuates wildly, Spain's Alvaro Morata might just have his work cut out in and around the penalty area tonight.
In captain Giorgio Chiellini and partner Leonardo Bouncci, Italy manager Roberto Mancini believes he has the best centre back pairing in the world. And Morata, a former team-mate to both at Juventus, is all too aware of what he is up against.
Back in 2017 before a World Cup qualifier, Morata described playing - and training - against Chiellini as 'like being put in a cage with a gorilla and you have to steal his food!'
Italy's Giorgio Chiellini comes up against Spain's Alvaro Morata again - just like at Euro 2016
The pair were team-mates at Juventus, with Morata shortly after saying competing against Chiellini as 'like being put in a cage with a gorilla and you have to steal his food!'
He continued; 'Who causes most problems for me? Chiellini... I think the few times I've managed to score against him it's been in the area.

Impossible, is it? That does not exactly bode well ahead of tonight's clash in the last four of a major tournament.
The pair first came accustomed to one another in the summer of 2014, when Morata joined Juventus from Real Madrid.
At 22, it was in Turin where the Spaniard made the first serious leap of his career, scoring 15 goals in a season which saw Juve win Serie A and reach the final of the Champions League.
Competing against Chiellini and Bonucci in training was a fire of baptism for Morata. But, by all accounts, he performed admirably during his two-year stay in Italy.

Fascinatingly, their first match-up against each other came just six days after Real bought him back, amid Euro 2016.
