This article forms part of our Total Duds feature series, which is where Football Transfer Tavern takes a look at how a player has fared since being signed or sold, using statistical figures and statements from pundits to prove how bad a deal the club got.

When Newcastle United captured the signing of Damien Duff for €15.5 million (£13.3m) from Chelsea back on the 1st July 2006, he had just won back-to-back Premier League titles under Jose Mourinho.

A man who would have been considered to be in his prime, the 27-year old was bought to try and get the Tyneside club to kick on, but nobody could have foreseen the disaster that was to come.

In his first season in the North East, Duff featured in 33 games in all competitions, but only managed one goal and five assists from the right side of midfield, according to Transfermarkt.

His market value dropped dramatically by the end of the campaign, as it started off at €15 million when he was with the Blues before falling to just €7.8 million.

Already, the fee paid for him was looking rather extortionate. Nevertheless, Duff had a chance to prove himself in the following term, and his market value did rise slightly to €8 million, before dropping again to just €6 million by the end of the season.

The former Irish international missed 17 matches with an ankle injury, but still managed 19 appearances in all competitions, only netting once, as per Transfermarkt.

It seems as if Duff never recovered based on what happened to him in the following campaign. Not only were the Magpies relegated under club-legend Alan Shearer, but the ex-winger scored an own goal that effectively sent them down.

He is perhaps partly to blame as the Toon descended into the EFL Championship. Nevertheless, Duff featured in 33 games in all competitions that term, but only managed three strikes and two assists, arguably not good enough numbers for a man who joins in the attacks.

Consequently, he was shipped off to Fulham on the 1st August 2009 for just €4 million, representing a huge financial loss. His market value ended up at a mere €5.7 million at NUFC.

Duff may have been a success at Chelsea, but based off the fee Newcastle paid for him, coupled with some unfortunate circumstances, the move ended up being a disaster.
