Riccardo Montolivo has conceded that Milan are in for a critical week as they face Hellas Verona and PSV in the space of four days.
The Rossoneri travel to the Gialloblu for their opening League fixture of the campaign and then host the Dutch side in the second leg of their Champions League play-off.
“On Saturday we have the first game of the season at a ground which will be sold out,” he told the club’s official website.
“And then on Wednesday we play PSV again.
“We are only at the beginning of the season, but we cannot afford to make any mistakes in either match.”
