Williams switched nationality from Spain to Ghana last year and went on to feature for the West African nation at the Qatar 2022 World Cup.
However, the Athletic Bilbao forward is yet to find the back of the net despite making seven appearances for Ghana.
The 28-year-old once again endured a frustrating outing when the Black Stars faced Angola last Thursday.
Chris Hughton’s side defeated the Black Antelopes 1-0 at the Baba Yara Sports Stadium in a 2023 Africa Cup of Nations (AFCON) qualifier on Thursday evening.
A 95th-minute strike by substitute Antoine Semenyo was the difference between the two teams as Hughton made a winning start to life as Ghana coach.
Gyan believes criticism of Williams is premature, insisting more opportunities need to be created for the striker to thrive.
In his view, the Spain-born forward will score lots of goals once he breaks his duck in the Black Stars shirt.
“It’s very difficult to adjust to the African game, He has played in Europe all his life,” Gyan, who is Ghana’s all-time top scorer with 51 goals, said.
“We need to give him more opportunities, he is improving even though he hasn’t found his feet yet but I’m sure his first goal will open the floodgates and many more will follow. His first goal will boost his confidence level. Let’s keep supporting him.”
Meanwhile, Hughton will hope to make it two wins from two games in charge when the Black Stars face Angola again on Monday, as they aim to wrap up qualification for the 2023 AFCON.
