Ahead of Tuesday's Uefa Champions League opener against Lille, former Ajax winger Tijani Babangida has picked Valencia has the main threat in Group H for Erik ten Hag's side.
Ajax will be looking to start their campaign on a winning note with the aim of matching and surpassing last season's feat in the elite European tournament where they were knocked out in the semi-final by Tottenham Hotspur.
In their bid to progress to the next round, the Dutch outfit needs to negotiate their way past group opponents Chelsea, Lille and Valencia.
