Andy Murray’s former coach Ivan Lendl has teamed up with rising star Alexander Zverev ahead of the US Open.

Zverev revealed the tie-up on Instagram, writing “Welcome to the team Ivan Lendl” and posting pictures of the Czech-American coach alongside him on court in New York.

It appeared to indicate that Lendl will be part of the 21-year-old German’s entourage for the grand slam at Flushing Meadows, which starts next Monday.

Lendl guided Murray to US Open glory in 2012 and two Wimbledon titles before they parted ways, for a second time, in November of last year.

Former British number one Greg Rusedski believes world number four Zverev has everything to gain from teaming up with 58-year-old Lendl, who won eight singles grand slams in his playing career.
