Eagle-eyed fans were quick to spot Leeds United new manager's curious drink of choice as he settled into his new office at Thorpe Arch training ground earlier today.
Marcelo Bielsa was pictured with a gourd used for serving a traditional caffeine-rich drink known as mate, or chimarrão, which is particularly popular in South America.
Prepared by steeping dried leaves of Yerba mate in hot water, which is then served using a metal straw known as a bombilla, the infusion is commonly consumed in Uruguay, Paraguay, Chile, Brazil and the manager's home country of Argentina.
And if you're keen to get a taste of the Leeds United manager's caffeine-rich drink for yourself, here are a five places in and around Leeds where you can stock up on the tea.
