Responding to criticism of the 27-year-old winger by a West Ham fan, Gold posted the following message on Twitter:
Ayew is a good player and cost 20m. dg https://t.co/ILVuQW4w9V— David Gold (@davidgold) February 11, 2017
Ayew joined West Ham from Premier League rivals Swansea City in the summer of 2016.
The 27-year-old winger has scored one goal and created four chances in 12 Premier League appearances so far this season.
A long-term injury has prevented Ayew from playing regularly for the Hammers this season.
Perhaps West Ham fans will not see the best of the former Marseille star in the final months of the season, but he is certainly going to be a hugely important player for Slaven Bilic’s side during the 2017-18 campaign.
The London outfit are 10th in the Premier League table at the moment with 32 points from 25 matches.
