Ajax have placed Chelsea defender Matt Miazga at the top of their summer transfer wish list, according to Soccernews.nl.
Citing US sources, the Dutch website says that the American international has impressed the Eredivisie side whilst playing on loan at league rivals Vitesse Arnhem over the past two years.
Miazga was signed by the Blues from New York Red Bulls in January 2016, and he is spending his second season on loan in the Netherlands at Chelsea’s feeder club.
The American has racked up 39 appearances for Vitesse so far and has three senior caps for his country. Soccernews.nl say that the Blues could be willing to sell the centre back for €8m (£7.1m) to Ajax if they follow up their interest with a formal bid.
The Dutch club sold Davinson Sanchez to Tottenham for €40m before the close of the transfer window back in August, and are keen to strengthen their backline.
