Houston quickly underlined the new alignment. "I know what he'll give me as my assistant and I want to make that perfectly clear - I'm the manager and he's my assistant," he said. "We've spoken at length about the situation and we're both very comfortable with our roles."
Rioch, 49, agreed to take the position within hours of the offer being made yesterday, despite being linked with a series of vacant managerial posts, including Manchester City.
Houston, who only took charge of Rangers this week after resigning as Arsenal's caretaker-manager last Friday, said: "I had a very good working relationship with him for the past year at Arsenal and I know what he'll bring to the club. His arrival shows QPR are an ambitious forward-thinking club. Bruce was out of work, so the opportunity arose for me to bring him in and he was delighted to accept."
Houston turned to Rioch after losing both Frank Sibley and Billy Bonds from the backroom staff at QPR within 48 hours of replacing Ray Wilkins. Only John Hollins remains from the old guard.
Manchester City, still looking for a manager, have signed Eddie McGoldrick from Arsenal on a month's loan and he could make his debut in today's game against Birmingham City at Maine Road. McGoldrick has not played in the Arsenal first team for over a year.
Another of the players Rioch and Houston left behind at Highbury, Nigel Winterburn, has been charged by the Football Association with bringing the game into disrepute following incidents during Monday's 4-1 win over Sheffield Wednesday.
The 32-year-old former England left-back is alleged to have made gestures towards Wednesday fans after Arsenal's second and third goals.
A Football Association spokesman said: "The player has been charged on the basis of reports filed by the referee Mike Reed and the fourth official, Paul Alcock."
Oldham Athletic have signed the 6ft 5in striker Ian Ormondroyd from Bradford City, but he was not registered in time for today's match against Barnsley.Reuse content
