The Argentine boss has warned his men against Schalke's attacking potency, and added that he will not rest any players ahead of this weekend's game against Barcelona
The Athletic boss feels that the former Real Madrid star is one of the best players in the history of the game, and has warned his team against Schalke's impressive attack ahead of the first leg.
"Schalke have great strength in attack. Klaas-Jan Huntelaar is showing what he's capable of week in, week out, and what can you say about Raul? He's one of the best players of all time," Bielsa stated on a press conference.
"Nevertheless, against Manchester United we managed to keep a very strong attack quiet so why shouldn't we do that again? What's important is that we don't walk straight into a trap. We have to avoid that at all costs."
The Argentine then went on to briefly look ahead to Saturday's match against Barcelona, and stressed that he will not rest any players for the Liga encounter.
"We will play our best available XI [versus Schalke]. We are not thinking about resting anyone ahead of Saturday's match against Barcelona."
The Europa League match at the Veltins-Arena kicks off at 21.05CET.
