Many have put Jurgen Klopp's recent selections down to simply the rotation that comes with the Premier League's hectic winter schedule, but there could be a more underlying concern behind Liverpool's latest line-ups - the compatibility of the fab four in the same starting XI without leaving the Reds too open at the back.

Even if that hasn't been a factor behind Klopp's starting XI calls in recent weeks, it will surely be on his mind ahead of a trip to Arsenal this Friday night. The Gunners have won all but one of their nine Premier League fixtures at the Emirates Stadium so far this season, scoring over two goals per match in the process.

So, Liverpool fans, if Klopp can't afford all of Philippe Coutinho, Roberto Firmino, Sadio Mane and Mohamed Salah on the same pitch, which three of the four should start against the Gunners on Friday? Let us know by voting below, giving your three picks a thumbs up and the last remaining of the quartet a thumbs down.
