Going unbeaten in the league would be a huge achievement though and I hope he doesn't throw that away.
But the FA or UEFA doesn't give you any extra awards/silverware for going unbeaten in the league :/
A golden trophy will be presented to them if eventually they stay unbeaten in premier league, it was given to Arsenal back then in 2003-04 Premier league season, it's a unique achievement if you ask me, it's worth playing his first team, regardless of the club he's playing in the Epl,
Even if you are given a golden trophy this will be forgotten in two years.
The win of the title will be remembered neither the unbeaten record nor the number of the unbeaten games Liverpool endured. Not point for me to play with his first team, it is better to do some rotation and win the Champions League along with the premier league. This would be a bigger achievement.
