Following Controversial Summer Transfer Speculations, Should Sanchez and Coutinho Remain on the Bench?

It was a long summer for clubs such as Liverpool and Arsenal who have done all they could to keep their respective star man in Coutinho and Sanchez.
If not for Mane’s red card against Man City, Liverpool looked comfortable even without Coutinho on the bench, while Arsenal won convincingly with Sanchez on the bench. Both players were desperate to leave their respective team with Coutinho aiming to join Barcelona while Sanchez hoped he could join Man City.
Unfortunately for the players, both deals fell through with their clubs insisting they are not willing to sell. Liverpool will be without Mane for the next 3 matches after he picked up a straight red card against Man City and Klopp may be tempted to call back Coutinho who could not make the bench in their last match even thou he represented Brazil during the International break.
Sanchez had came off the bench in the last two matches, and was unable to make real impact. He was booed by the fans in the last game and it was pretty much understandable the reasons for that.
Do you think both players should be kept off the first team or they should be called back?
