Modeste was heavily involved on his full debut.
Kean said of the Bordeaux man: "I think Anthony did well. He was unlucky not to get a goal, he probably had enough chances to get a hat-trick, but each time it fell to him and it didn't happen, maybe he just tried a little bit too hard.
"But I think he showed enough tonight that he's going to add something to our squad. He didn't know he was going to play until the very last minute because David Goodwillie had flu so maybe just a little bit of over-excitement on his part."
