VDB played in the double pivot against Instambul Basaksehir in the UCL, Leicester and Wolves in the PL, and Watford in the FA Cup. In the first 3 he played with Matic, and against Watford it was with Scott. Also, he played more deep for Ajax a lot of times, especially after De Jong's departure. He is an option.
Also, we signed 3 world class players and i think that counts as the best windows of the top 4 clubs. Let's see: Liverpool only brought Konate but failed to replace Wjinaldum and add more depth to their attack.
Chelsea apparently won't bring Saul anymore and Kounde is looking unlikely each minute, so they only really brought Lukaku. It's a good sign, but they are one injury away from having to play Werner as the striker. Also, not much depth behind Kante-Jorginho-Kovacic. Also, they have 4 CB, and play with 3 at the back, so lack of depth, that's why they wanted Kounde.
City brought 100m Grealish but then it was failure after failure. With Kane, Ronaldo... They lost Aguero and replaced him with nobody. I know Pep likes to play with a false 9, but it helps when you have a proper striker as an option.
Also, Leicester and Tottenham had a good window. They've kept their best players, and brought some reinforcements.
So, nobody has had a perfect window and addressed every hole they needed. I think we came closer with 3 world class players. We should challenge for the title, there are no guarantee, but we should be in the conversation by the end of the season.
