The Leeds United hitman has been known to score against Wigan Athletic.
Bielsa has top goalscorer Kemar Roofe fit again after a two-month absence and Bamford has only netted twice in his last six Championship games for Leeds.
He isn't a player bang in form and with Roofe available, few Whites supporters would question the decision to drop the former Middlesbrough hitman, who moved to Elland Road for £7 million last summer [The Daily Mail].
But before he does, Bielsa needs to know Bamford's history against Wigan - and in short, the 25-year-old has been known to score against them.
He has only faced them on two occasions but Bamford has managed to score three times against the Latics.
Strikers like facing certain teams and it's clear that he enjoys facing Wigan, which means that Bielsa should think twice about dropping him, even if there's good reason to.
He has only scored two or more goals against four other current Championship sides - Leeds being one of them - and the Argentine should let him try build on that purple patch against Paul Cook's side this Friday.
