Klopp hit the jackpot when he chose Jota from Wolverhampton instead of Werner, he was aware of the role and characteristics of his fellow countryman
If Klopp was aware of all things about Werner, he did not buy any jackpot. What happened with Werner is unbelievable and just a continue of Chelsea failures with strikers. Under the era of Abrahimovich, only Diego Costa is the successful striker for Chelsea. All others are failures.
Jota is a very good contract for Liverpool and Klopp and it is more meaningful for them in the season Firmino shows his very bad form. If Firmino won't be able to take his good form back, Jota will take over the official position from him. That guy also has very good matches in Portugal skirt. There are some players who only play well as substitutes from the bench but Jota might not be such players.
