Well, this is certainly not ideal, regardless of what opinion you may hold of Branislav Ivanovic's skill and place in the team. The man who's been indispensable to the squad since the days of Carlo Ancelotti is in danger of missing the start of the season thanks to the shoulder injury he picked up against Wolfsberger AC earlier this week, which has now been diagnosed as a dislocated shoulder with a three-week recovery time.
There's little reason to think that the Mail aren't working with accurate information here. Their report does mention that the injury is "not thought to be serious" and that Ivanovic would still travel with the squad to the USA, but at the very least, it disrupts his and the squad's preparations for the new season. Ostensibly the first-choice right back at this moment, even if Ivanović recovers in time for the season opener (also in three weeks, just as the prognosis), he will likely not be at the same level of fitness and tactical understanding as the rest of the team.
Conte has featured young Ola Aina a fair amount so far this preseason — perhaps this opens up an unlikely opportunity to impress for the 19-year-old, who, just like César Azpilicueta, is comfortable playing on either flank.
