"The important thing is for him to keep calm,” said Bastoni. “Everyone can make mistakes. So there’s nothing to worried about.
“It’s a bit weird, because Inter conceded so few goals last season and it always took so much to score against us.
“But we’re just at the start of a 38-game season, so let’s move forward without overreacting.”
Bastoni also lamented, “Obviously we have to adapt to an increasingly busy fixture list.
“Twenty days off can’t be considered a real vacation.
“Mentally, managing having so many matches is tricky. Particularly with a fixture list that never seems to end.
“But we’re here to play,” Bastoni said. “And we’ll give our best in every match.”
