Cascarino sees Sterling as a replacement for Timo Werner.
â€œI think they'll do at least two big signings before the start of the season," he told talkSPORT.
â€œI think that Raheem is perfect for Chelsea, I think that they need that kind of player.
â€œI love Raheem's pace. There are so few players who can get to the byline as a wide player. Timo Werner is a terrible finisher, now some people say that Sterling's finishing is not the greatest but he always gets chances and he always gets a decent number at the end of a season."
