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.

Tottenham have not always had the best of luck in the transfer market.

The spending after the sale of Gareth Bale is likely to be a period that many Spurs fans would rather forget. With the money from the Wales international's departure to Real Madrid, the likes of Paulinho, Roberto Soldado and Vlad Chiriches made the switch to White Hart Lane - only Christian Eriksen has proven to be worth every single penny.

There have been other mistakes since then as well, such as the signing of Vincent Janssen. It is fair to say the Netherlands international had a torrid time in north London.

The Lilywhites paid £18.6m to AZ Alkmaar for him in 2016, and at the time it was a move that made perfect sense. He had just come off the back of a season in which he scored 32 goals in all competitions, including 27 in 34 league matches, and at the age of just 22, he was one for the future.

However, it is fair to say his time at the club was nothing short of a disaster. In his first campaign, he managed just six goals in 38 matches in all competitions, with four of those coming in the domestic cups. He would make just one appearance for the side in the 2017/18 campaign, joining Fenerbahce on loan in September of that term.

After five goals in 17 appearances in Turkey, he returned to England, but would play just three more matches for Spurs. Last summer, he joined Mexican side Monterrey for £6.3m, meaning Tottenham made a loss of £12.3m in three years and just 42 matches as Janssen completely flopped.

Daniel Levy has a reputation for being a sturdy negotiator, but this is one transfer he got terribly wrong.
