Watch as Frank Lampard addressed the press ahead of his side's Premier League game against Leeds this weekend.
Lampard and Bielsa will face off for the first time since the 2019 play-offs in the second-tier Championship, when Derby, then managed by Lampard, beat Leeds at the end of a turbulent campaign.
Bielsa sent a member of staff to spy on Lampard's Derby in training in January 2019, later admitting he had snooped on every club he had faced. The Argentine was forced to pay an English Football League fine of £200,000 ($270,000).
But Lampard, who was highly critical of Bielsa at the time, has joined the Leeds boss in attempting to dampen down any talk of a lingering feud.
