Murray jokes about Madrid discovery: "After years of being miserable, I wish I'd know that all I needed was coffee"

Andy Murray has been in a humorous mood as of late and that could be the effect of a discovery from the former World Number One.

That being coffee and Murray joked on his Instagram that after all of these years of being construed as grumpy and miserable by some, all he needed was caffeine.

This comes after he has spent the past few days continuing to take digs at Liam Broady as well as followers dropping after Elon Musk's purchase of Twitter.

"After years of being miserable and incapable of smiling I wish I’d known that all I needed was a coffee," said Murray on Instagram.
