Christian Pulisic of Dortmund for me. He's 17 so he can one day count towards your home-grown at club quota. A starter for most premier league teams, and isn't terribly expensive: I got him for Liverpool 14 mil pounds + 4.5 in long term add-ons.
Scottish winger, Oliver Burke at RB Leipzig? Valued at £8m - might be able to get him cheaper?
I started unemployed and now managing Weston Super Mare in the Vanarama Conference South - so not much point me putting a bid in for him. All my players and staff are Part-Time! XD
