Yes accept it and go and buy Memphis Depay from PSV and also keep tracks on Bakkali as you can approach to sign in jan thse two become world class on this game and will get you a ton of goals from the wing.
Depay is ready for first team now i would defo recommend him then approach to sign bakkali in jan.
Then 2-3 years down the line you can sell Depay for around 50-70million and bakkali will have developed enough to be more than a suitable replacement and in which could solve your rm/rw problem for next 5 years atleast
