The young Leeds United goalkeeper is back from a spell at York City.
The young goalkeeper recently returned from a month-long spell at York City, for which he received mixed reviews.
But after making his first appearance of the season for Leeds' Under-23s last month, Peacock-Farrell looks to be back on the up.
And based on the 21-year-old's latest Twitter post, that could spell further bad news for Lonergan.
Lonergan recently lost his place following a seven-game run in Thomas Christiansen's starting 11, and has seen the performances of Felix Wiedwald justify that decision.
As a result, the 34-year-old, who returned for a second spell at Elland Road from Wolverhampton Wanderers in the summer, may be wary of falling further down the pecking order should Peacock-Farrell catch the eye of Christiansen.
Peacock-Farrell has only played once for Leeds' first team to date, but signed a new three-year deal ahead of his move to York this autumn.
Should Peacock-Farrell be Leeds' second-choice goalkeeper?
