Antonio Nocerino admits AC Milan teammate Antonio Cassano's heart problems left the players stunned.
Cassano had the ischemic attack on the plane back from last Saturday's 3-2 victory at Roma, resulting in blurred vision, difficulty speaking and walking.
"When we found out about Antonio, we were all perplexed and sad. It really hit us hard, too," Nocerino told Milan Channel.
"We really did not realise at the time what was going on, but afterwards we all worried, as we couldn't figure out what was wrong with Antonio.
"Now he is better, he's strong and just has to focus on resting so he can come back better than ever. We all await him with open arms."
