Gyan was not at his prolific best due to an injury he was carrying and got pilloried for his sterility.
The criticisms from fans severely hit the then 22-year-old who felt unappreciated after making a huge sacrifice.
He parked his bag to leave camp but rescinded his decision after talks with the Ghana president JA Kuffour.
According to Gyan, playing in his first Nations Cup tournament aggravated his injury which denied him a move to Manchester City.
”I regret playing at the 2008 Africa Cup of Nations because I was injured but I felt I needed to sacrifice but yet I was criticized,” Gyan said on GTV’s Sports Highlights show as monitored by TheBBCghana.Com
”I really regret playing in the tournament, because even after that I had to go out for five months.
”I was supposed to sign for Manchester City but I missed. That has been one of my biggest regrets with the national team.”
Gyan scored just one goal at the tournament- a penalty in the tournament opener against Guinea.
The former Sunderland later featured in six other Africa Cup of Nations and is the country’s top scorer in tournament history with eight goals.
