Bielsa was talking ahead of Leeds clash against QPR on Thursday afternoon.
Marcelo Bielsa has been quoted by Leeds Live as saying that there will be little action in the January transfer window, as he would prefer to work on his current players - which has been met with concern from Leeds fans on Twitter.
Leeds are suffering an injury crisis, which has already seen Jamal Blackman return to Chelsea. In defence, Stuart Dallas, Liam Cooper, Luke Ayling and Gaetano Berardi are all injured. Izzy Brown and Patrick Bamford are close to a return.
Bielsa is likely to name a makeshift defence on Saturday afternoon at Elland Road against QPR after Dallas and Cooper were ruled out this week, with Jamie Shackleton and Aapo Halme expected to come in.
Ahead of Saturday's clash against QPR, Bielsa was asked about whether he would look to bring in defensive and goalkeeping reinforcements in January, but the Argentine remained unmoved on his transfer policy.
"For the second part of the season, when you buy a player it has an impact on the club finances because the big players are not easily available. Apart from the situation where the team needs someone, we won’t buy anyone," Bielsa said.
"I prefer instead of buying to improve the quality of the work because the team usually reflects the quality of the players’ individualities, but it’s also linked to the training and you also can improve a team when you improve the equipment."
Leeds currently sit in second place in the Championship table and fans are beginning to get excited of a potential promotion back to the Premier League for the first time since relegation in 2004.
So fans became instantly concerned when hearing Bielsa state that he would not look to bring in any players in January, unless it became crucial to do so. One fan Tweeted: "Really hope this doesn't come back to haunt us."

There has to be some signings, can understand he doesn’t want to just bring in players for the sake of it but we are severely lacking I certain areas even with everyone fit.— Nathan Phillips (@NathanP92) December 6, 2018
A few loan signings from his friends at Man City and Spurs with an option to buy would greatly help us in promotion run in.— Hound of Ulster (@JimA1964) December 6, 2018
Rubbish but not unexpected with this owner— CM (@Chris_Moulds1) December 6, 2018
Expensive being the operative word here. The owner doesn’t want to part with any more cash. Gonna be a long 2nd half of the season if we’re not careful!— Wooly Sammoth (@Oli_Ginger_King) December 6, 2018
Will regret it if they dont bring anyone in, every other club at the top will be improving— Danny Robinson (@danny_robinson2) December 6, 2018
