Speaking to reporters, the Frankfurt boss said: "He’s only played a total of four games in the last two years, so it won’t happen overnight. But I have 100 per cent confidence in his quality, he’ll definitely help us in the second half of the season. I told Donny that I was sorry but also what I expected from him now."
Van de Beek recently featured in a behind-closed-doors practice game against the club's U21 side where he provided two assists and scored one goal. Toppmoller was left impressed with the Netherlands international's performance as he added: "That showed me that he can handle the decision well. He is ready to take on the challenge."
