Liverpool have already had a productive transfer window but now manager Jurgen Klopp is already plotting his next big arrival – in the summer of 2019 – Dortmund wonder-kid Christian Pulisic.

The German already has a great relationship with the Pennsylvania born teenager after bringing him to Dortmund when Pulisic was just 16.

Dortmund have stated their firm desire to hold onto the USA international but Klopp is patient when necessary to get a player he really wants.

The precedent was set with RB Leipzig’s Naby Keita. Liverpool signed him in the summer of 2017 with the agreement that the Guinea-midfielder would not arrive on Merseyside till summer 2018.

That move has now finally transpired and judging on Keita’s appearances in pre-season he was well worth the wait.

Now Klopp is plotting a similar timeline to prise the talented Pulisic from Dortmund.

The German club are reticent to let Pulisic leave now but by this time next year he will have just one year left on his contract and Dortmund will be far more willing to sell, or risk losing him on a free transfer the following season.

Klopp has already outlined this summer his glowing admiration of the talented teen.

Even more so after Pulisic came on at halftime in the International Champions Cup clash in Charlotte and single-handedly inflicted the Reds only pre-season defeat, scoring twice and assisting in a third.

Klopp also still has money to spend with Lyon’s Nabil Fekir’s £53m transfer from Lyon collapsing, and unlikely to be re-visited.

The Liverpool Echo says Klopp is not prepared to spend £60m/£70m on a squad player this summer but the club are expected to make a fresh move for the Bundesliga talent in 2019 – a deal that could be agreed in this window.
