cup formats are different from league formats. that's why liverpool won the champions league, like Chelsea, milan and real, without winning the league and even with poor results in the premierleague.
werner, mount and havertz aren't doing any better than they did with us and. From what I read, a good number of united, arsenal and even tottenham fans are suspicious and unenthusiastic about them.
havertz has had some good moments, but he's fallen off the pace and has only scored 5 goals in 14 games with arsenal this season to premierleague. that's nothing different from what he did with us, and werner has only scored 3 goals in 33 games for tottenham in the last two years he's been at the club, and even at leipzig he didn't do anything special.
mount is constantly injured and is called just a nothing player.
we've made the right decision on all three in order to move up in the premierleague
