Jurgen Klopp has a big call to make with regard to his Liverpool attack for Sunday's Premier League game against Arsenal.
Since his arrival on Merseyside seven years ago, the German has guided the Reds to success in the Premier League, Champions League, FA Cup, Carabao Cup, Super Cup, the Community Shield and the Club World Championship, all whilst deploying a 4-3-3 formation.
However, in an attempt to arrest his side's disappointing start to the season, the German tweaked the system for Liverpool's 2-0 win over Rangers in Europe earlier in the week. He set his side up in a 4-2-3-1 shape, allowing him to unleash Mohamed Salah, Darwin Nunez, Diogo Jota and Luis Diaz in attack.
