Mazzarri favours a 3-5-2 system, which employs three centre-backs and two wing-backs, who patrol the flanks.
With the legendary Javier Zanetti now gone, there are several players in the squad who can fulfil the right-back role, though the most likely to start there is Jonathan.
The Brazilian is dependable and hard working down the right, even if he lacks the flair of some of the great players from his country in that position.
Danilo D'Ambrosio is the other player in the squad who most naturally suits the role of full-back and could end up being the coach's first choice. Like Jonathan, he is competent in the position but not quite world class.
There are others who could fill in at right-back if required, such as Hugo Campagnaro, who normally plays in central defence, and Gary Medel, who can also be utilised in midfield.
Overall, it is not Inter's strongest position, though Mazzarri at least has plenty of cover.
