“Coutinho has also just signed (a new contract), and that shows the club has got a great future with young players. It’s great that young players are signing these contracts for the club,” Can told the Liverpool Echo.
Liverpool have one of the youngest sides in the Premier League and several stars including Countinho, Raheem Sterling and Ibe Jordan are all under the age of 21.
Henderson extended his Liverpool deal to 2020 this week and is expected to replace outgoing Liverpool captain Steven Gerrard next season.
The 24-year-old joined the Reds on a £16m move from Sunderland in 2011.
Can joined Liverpool as a midfielder from Bayer Leverkusen in the summer but has featured mainly as defender in Brendan Rodgers back-three.
The 21-year-old has three-years left on his current deal.
