Justin Kluivert will wear shirt number 34 for Roma in tribute to his former Ajax team-mate Abdelhak Nouri.
The Netherlands international completed his switch to the Serie A side from Ajax for €17.25million last month.
Nouri was left with permanent brain damage after experiencing heart failure during Ajax s friendly against Werder Bremen in July 2017.
And Kluivert announced on Saturday he will honour Nouri in his choice of shirt number at Roma.
Why 34? Appie s number, Kluivert wrote on social media. My prayers and shirt number for you, my friend-brother who taught me so much.
34

Last month, Ajax confirmed a review of the on-field treatment received by Nouri was inadequate .
Managing director Edwin van der Sar said: We recognise our responsibility and liability for the consequences of this.
