Burton Albion manager Nigel Clough says the sale of forward Nasser El Khayati was in the best interests of the club.
The 26-year-old Dutchman signed a two-and-a-half-year deal with QPR for an undisclosed fee on deadline day.
Clough told BBC Radio Derby: "The player wanted to go and that's crucial. If you keep him against his will, what sort of frame of mind will he be in?
"But we think it was a good enough deal for the club and we think the squad is good enough."
El Khayati, who joined Burton just over a year ago from NAC Breda and scored 11 goals in 42 league appearances, links up with his former manager Jimmy Floyd Hasselbaink.
The Brewers are top of League One and three points clear of third-placed Gillingham, but were beaten 2-1 at Rochdale last weekend.
Clough continued: "We sat down with the chairman and if you think it would completely ruin your promotion hopes you don't do it, but we don't think that is the case.
"He's a smashing lad, he's done brilliant for the team and goes with everybody's best wishes.
"I don't see us as a selling club but if an offer comes in for a player to go to a higher level and it's a good offer, then it's difficult for us to turn down."
