Ajax have edged closer to the knockout stages of the NextGen Series thanks to a goalless draw at Chelsea.
A win for either side would have seen them book a place in the next round with Group 3 leaders CSKA Moscow, but they both failed to find the target.
The result sees Ajax lead the Blues by two points with just one game remaining.
The hosts created the better chances in the first half through Islam Feruz and Lewis Baker.
Lesley de Sa missed a decent opportunity for Ajax with 20 minutes left to play before Baker was denied again late on.
