Ajax will look to recover from the disappointment of last season's European heartbreak as they begin the new Champions League campaign at home against Lille.
The Eredivisie giants made a surprise run to the last four in 2018/19 and looked set to reach the final only for a 96th-minute effort from Lucas Moura in Amsterdam to send Tottenham to Madrid on away goals.
After beating PAOK and APOEL to secure a return to European football's elite club competition proper, Erik ten Hag's Dutch champions were placed in Group H alongside Chelsea, Valencia and Lille.
Lille - last season's Ligue 1 runners-up - are appearing in the Champions League for the first time since 2012.
