Leeds United are the last club to tempt fate as far as promotion is concerned.
However, in the modern era of recruitment, the Whites must have one eye on how to bolster their squad should they reach the Premier League.
With nine Championship matches left to play, Marcelo Bielsa's side are in prime position, top of the league with a seven-point buffer on Fulham in third spot.
As a result, work may already be ongoing in the background to ensure Leeds have a squad capable of challenging in the Premier League.
Having watched Aston Villa overrecruit and disassemble their promotion-winning team and Norwich City underinvest, United will be keen to strike the right balance.
Here, we take a look at the best free Premier League free agents that could be shrewd additions for Bielsa's squad.
