The Dutch midfielder is full of praise for the Real Madrid tactician and is hopeful that the two will work together again in the future
Van Marwijk has a contract with the KNVB until after Euro 2012 and the former Feyenoord tactician recently expressed his desire to take the reins at a foreign club.
"If Oranje want to have the best of the best as national team coach, they should go for Mourinho," Sneijder was quoted as saying by NUsport.
"He has what it takes to keep an entire team satisfied. Not only the starting XI enjoys working with him, but the substitutes as well.
"He will always be the undisputed number one for me. I have never heard any player talk negative about him. I have a feeling that we will work together again at some point in my career."
Sneijder previously worked under Mourinho at Inter in 2009-10 and won the Serie A, Champions League and Coppa Italia when the Portuguese tactician was in charge at Giuseppe Meazza.
