The Bianconeri director believes that his side's Champions League draw could have been worse but warns of the threat posed by Galatasaray as well as just Real Madrid
The Bianconeri, who reached the quarter-finals of the last year's competition, were seeded in pot two and Marotta accepts that the group could have been far tougher.
"It is a draw of medium difficulty. It could have been better, could have been worse," he told reporters.
Marotta also warned his troops that they must be wary of Galatasaray, particularly on the trip to Istanbul.
"We believe that, while Galatasaray were in pot three, they are a very good side and got to the quarter-finals last season, which proves they are tough," he remarked.
"They won a trophy in the last few days in Turkey and, in Fatih Terim, they have a great coach. We know that the fans can make it tough but they're also difficult opponents."
Paris Saint-Germain were also second seeds but were handed a seemingly easier group, with Benfica, Olympiakos and Anderlecht as competition, but Marotta feels that the French champions will still have their work cut out.
"It's a group of many possibilities," he observed. "There are still four teams in there that can make anything happen."
PSG striker Zlatan Ibrahimovic, who represented the Turin giants earlier in his career, has never won the tournament but the 56-year-old believes that the Swede could still claim Europe's top prize before calling it quits.
"He remains a top player and he has a lot of quality," Marotta added, "so you can't say it will never happen for him."
