I think that’s a good signing for Ajax. With the loss of Younes and Kluivert, they are in need of a creative winger who can play in multiple positions.
With Tadic, Erik ten Hag can now play the typical Ajax 433 and his Utrecht 4312. Neres, Dolberg and Tadic as a front three with Neres and Tadic switching wings during the match or Tadic behind Dolberg and Neres in more of a fluid Brazilian 4312. Both systems could even cross during the match, 433 high press out of possession and 4312 in possession for example.
They could still do with a proper left winger though for squad depth.
