Owen Coyle says he is in favour of goal-line technology but believes all other decisions must remain with the referee.
Coyle's side, who face Tottenham in the FA Cup quarter-finals on Saturday, were the beneficiaries last weekend when QPR were not awarded a goal when the ball had clearly crossed the line.
The International FA Board have given the green light to final tests on two goal-line systems but Coyle believes technology should stop there.
He said: "For me goal-line technology would help to improve the game and we have seen in the World Cup, when England played Germany that game could have turned out totally different if Frank Lampard's goal had been given.
"I don't think it should be tampered with beyond that though - sometimes you can look at something five, six or seven times and two people still don't agree because they see it differently."
