2. Marco Reus
The one player that everyone would want to see at Liverpool would be Reus. The attacker might have had a poor time with injuries last season but this season he has been on fire under Tuchel and would make a great addition to Liverpool, who need a decent winger.
Speed, ability to finish and a team player, Reus has everything to succeed in the Premier League. The transfer fee might be a bit steep, but you have to pay that amount to get the best players into the team. If there is one position apart from the central defenders, it is the wings which need a bit of touch-up at Liverpool and that can easily be done by Reus.
