The midfielder is regarded as one of the hottest prospects in German football and he already has plenty of admirers.
Barcelona have been tracking the 22-year-old for over a year, while he has been linked with Paris Saint-Germain in the past too.
Now, according to AS, Manchester City have also joined the race for Weigl after watching him in action.
Manager Pep Guardiola is said to be a big fan of the German and he could be on the hunt for midfielders next summer.
Both Fernandinho and Yaya Toure will be out of contract at the end of the season and Weigl could come in as a replacement.
