David Ngog has completed his transfer deadline day move to Bolton, his former club, Liverpool, have confirmed.
The French striker moved to Anfield from Paris St Germain in 2008 with a big reputation, but he was forced down the pecking order by the arrivals of Andy Carroll and Luis Suarez.
Bolton as a result spent most of this summer chasing Ngog and have now got their man on what is understood to be a three-year deal.
Liverpool are reported to have received £4million from the sale, which represents a £2.5m profit on the fee they paid PSG.
A statement on the club's official website read: "Liverpool have tonight confirmed that David Ngog has completed his transfer to Bolton Wanderers."
The statement added: "Everyone at Liverpool FC would like to wish David all the best with his future career."
"David will be a great addition to our squad," Coyle, who has also signed Gael Kakuta on loan from Chelsea, said.
"He is quick, can score goals and he knows what the Barclays Premier League is all about.
"Added to that there is his European experience with Liverpool in the Champions and Europa Leagues.
"He has represented his country at a host of junior levels and he will offer our team further attacking options.
"We are delighted to bring another quality, young prospect to Bolton."
