West Brom handed Luton EFL Cup test, Bielsa's Leeds host Bolton
Relegated West Brom will begin their EFL Cup campaign against League One Luton Town, while Marcelo Bielsa's first taste of the competition will come as Leeds United host Bolton Wanderers.
The Baggies entered in the first-round draw after finishing bottom of the Premier League last season, with fellow relegated sides Stoke City and Swansea City given a bye.
Darren Moore – who was handed the permanent manager's job after impressing following Alan Pardew's departure – will welcome League One new boys Luton to The Hawthorns in the opening weeks of the new campaign.
Hours after appointing Bielsa, Leeds were drawn at home to fellow Championship side Bolton, while Frank Lampard's first taste of cup football as a manager will come at Boundary Park as Derby County travel to Oldham Athletic.
Bristol City will face Plymouth Argyle for the second successive season, the Robins hoping they can replicate their run to the semi-finals in 2017-18 that included a memorable victory over Manchester United.
Meanwhile, Macclesfield Town and Tranmere Rovers – promoted back to the Football League last month – were drawn against Bradford City and Walsall respectively.
