Liverpool took on Burnley, you kid of sense that now it is.

Roberto Firmino and Fabinho did not look too fatigued when they were spotted at Melwood on Thursday, but with games against Napoli and Chelsea on the horizon of Steve Bruce's side.

Nominally seen as an attacking player, Lallana has been converted to a 'No. 6 'over pre-season maybe to try and prolong his Liverpool career, with both player and manager
It's against Lyon in the clash in Geneva.
Klopp wants to use him in the Carabao Cup at MK Dons later in the month.
