Liverpool won the FA Cup at the expense of Chelsea on penalties on Saturday to achieve a domestic double so far in winning the League Cup.
After winning 6-5 on penalties at Wembley, Klopp told reporters: “Let’s see what happens. If City lose to West Ham, I’ll start thinking. If they don’t lose, we’ll decide to retire,” according to Reuters.
Liverpool are three points behind Manchester City and trailing on goal difference going into the last two league games.
Manchester City will visit West Ham on Sunday, and the difference may widen to 6 points, and then they will need a point from the last game of the season to retain the title.
Liverpool will also play the Champions League final against Real Madrid in Paris on May 28.
The German coach hopes to make changes to his squad when he visits Southampton on Tuesday after playing extra time against Chelsea.
The position of Salah and Van Dyck
A medical on Sunday will determine the position of striker Mohamed Salah and defender Virgil van Dijk, after they were substituted in Saturday’s game, but Klopp does not believe either will be seriously injured.
“I think they are fine,” Jurgen Klopp said.
He also praised Colombian winger Luis Diaz, who joined Liverpool last January from Porto after posing a constant threat to Chelsea.
“What a boy, what a story, but he should have scored, he fits us perfectly and that’s really special,” Klopp added.
Saturday’s achievement means Klopp became only the second manager to win the European Cup or Champions League along with the FA Cup, League Cup and English Premier League with the same team after Alex Ferguson with the Man Utd.
