Chatto was born in Kaduna, Nigeria. Chatto started playing football in the age of six. He developed into one of the most talented players of his region and was always chosen to lead his team as a captain. Chatto learned to play football in Pepsi Football Academy in Nigeria. Before moving to Nigerian Premier League and Heartland FC he trained also in Highlanders Football Academy. In the league he succeeded so well that, in 2005, he was given a tryout in Blackburn Rovers. Eventually, he did not get a work permit, because he had not played in 70 percent of national team matches. Despite this, Blackburn and Mark Hughes wanted to sign a contract and send Chatto to Cercle Brugge for a loan. Chatto refused to go to Brugge, because he would have had to wait three months to get a playing right for the Belgium league. After England, he visited Dynamo Kyiv and Brøndby IF, but did not get a contract offer. He chose to go back to Nigeria and wait for new offers from European clubs.
His professional career in Europe started in 2007, when Finnish Veikkausliiga club FC Inter Turku signed him. In his first season, he was voted as the third-best player in the league and was called up to the Nigerian under-23 national team. After the season, he signed a new year-long contract with the Turku-based club. In the 2008 season, Chatto was linked with a move to Slovakian FC Senec, Serbian FK Partizan and Red Star Belgrade. The owner of FC Inter refused to sell without a large transfer fee and Chatto stayed in the club. In the last match of the championship season Serie A club Atalanta B.C. was scouting Chatto. Some Russian league clubs were after him and also FC Inter offered him a new contract and was hoping to keep the player. After the season 2008, Chatto was voted for Veikkausliiga players' player of the season.
In November 2008, Chatto signed a three-year contract with just promoted Swedish club BK Häcken. Häcken had to pay a transfer fee to AS Racine, which still owned his rights. The transfer negotiations started when former Finnish international Janne Saarinen contacted Chatto via Facebook. Chatto scored a goal against IF Elfsborg in a pre-season friendly. In an interview before the Swedish season, Chatto said that Häcken were hoping for a survival in the premier division, but he hoped that they could reach a top-five place.
