In early 1968, he moved abroad to play professionally for American team Houston Stars in the NASL championship. Due to the Danish rules of amateurism, his national team career went on a hiatus. He played the 1968 season for Houston Stars, When the team folded after the season, Bjerre moved back to Europe. He went on to play for PSV Eindhoven in the Netherlands. In 1969, he moved on to Belgian club R.W.D. Molenbeek. He was one of the best paid footballers in the Belgian League, and was the first foreign player to be named team captain in Belgian football. While at Molenbeek, the Danish rules of amateurism were abolished, and Bjerre re-entered the Danish national team in May 1971. He played 14 additional national team games, scoring a further four goals. In his last 13 Danish national games, Kresten Bjerre served as national team captain.
The lacking professionalism of the Danish national team did not sit well with Bjerre, and he became a Belgian citizen in order for Danish international Benny Nielsen to take his place in Molenbeek's restricted quota of foreign players. This meant Bjerre's final farewell to the Danish national team in November 1973, though he changed back to Danish citizenship after retiring. Bjerre went on to concentrate on his Molenbeek career, and won the 1975 Belgian League championship with the team. He was a part of the Molenbeek team that reached the semi-finals of the European 1977 UEFA Cup tournament, before retiring at the end of that season.
