Career
He scored a single goal in seven games for the Denmark national football team Born in Copenhagen, Chrøis started playing football with local team Boldklubben Avarta. He made his senior debut at Avarta, and established himself as a defensive midfielder with fine finishing.
In 1981, before the 1982 season, he became the first fully professional player in Danish football, when Brøndby chairman Per Bjerregaard offered him a full-time contract.
He was Brøndby"s topscorer with 13 league goals in the 1983 season, and was called up for the Danish national team in May 1983, by national manager Sepp Piontek. He played seven games in Denmark"s unsuccessful qualification campaign for the 1984 Summer Olympics, scoring a goal against Norway.
In 1984, he was offered an economically improved full-time contract by Brøndby"s rival team Hvidovre IF, which he accepted. As Bjerregaard did not want his young midfielder moving to a rival club, he used a clause in Chrøis" contract, to sell him to a foreign club
Chrøis moved to Spanish club Granada CF in the secondary Segunda División league.
He enjoyed life in Spain, but he was soon far from the Danish national team, and decided to move on after a year. This caused problems getting his wage from Granada, but with the intervention of Per Bjerregaard, Fédération internationale de football association got involved, and Chrøis received the approximately £25.000 the club had withheld. He moved to Switzerland, to play for Air Corps Bellinzona in the secondary Challenge League division.
Brøndby hired new manager Morten Olsen in January 1990, and Chrøis was one of several older players who did not feature in Olsen"s plans for the future.
Chrøis moved to lower league club Helsingør IF, alongside Brøndby players Erik Rasmussen and Ole Østergaard. He played one and a half year at the club, before an achilles tendon injury forced him to retire in 1992.
He went on to coach Helsingør alongside Birger Peitersen, and coached a number of smaller Danish teams before leaving football in 1998. He later returned to football and coached Humlebæk BK and Allerød FK.
