In March 2007 he won the Football League's Apprentice of the Year award after impressing in the first team squad due to injuries to some regular players and during the summer of 2007, Gunter was the subject of two bids of £500,000 and £1 million from Premier League club Everton. Both, however, were rejected. At the end of the 2006–07 season, having made sixteen appearances in all competitions, he became Cardiff's youngest player to win a senior international cap after making his debut, beating the 48 year old club record held by Graham Moore.
