After 14 Premier League goals in two seasons for Reading, Stoke felt confident that Kitson would fit in with Tony Pulis's direct style of play, paying £5.5m to bring him to the Britannia Stadium upon the Potters' promotion to the top flight. Yet after a goalless debut season and just five goals in his second campaign, he was sent to Portsmouth in swap for Marc Wilson, meaning Stoke paid £1.1m for every goal he scored for the club. That's not good value for money.
After Stoke stayed up in their first season, Pulis tried to bring in a better standard of player, swooping to sign Middlesbrough's Turkish international striker Tuncay for £5m in 2009. Sanli offered flashes of brilliance here and there, but his record is a testament to his time at Stoke; eight goals in 55 games just wasn't good enough, and he was sold to Wolfsburg after just 18 months at the Britannia Stadium
One of the more bizarre Pulis signings. Arismendi was highly thought of in his native Uruguay having broken through with Nacional, and Pulis felt that was proof enough that he was worth £2.5m. Well, the midfielder played just six games for Stoke, none of which came in the Premier League. After loan spells with Brighton, Barnsley and Huddersfield, Arismendi returned to Uruguay with Nacional after a disappointing spell in England.
Palacios might take the crown for the worst Stoke signing since their promotion to the Premier League. The Honduran had earned a reputation for being a combative midfielder during spells with Birmingham, Wigan and Tottenham, and having slipped down the pecking order at Spurs, Pulis forked out £8m to bring him to Stoke in 2011. The 30-year-old has yet to even get on the pitch this season, and looks set for a loan move to Brighton after an ineffectual spell with the Potters - money down the drain from Stoke's perspective.
Giant Senegalese centre back Sonko had impressed with Reading, much like Kitson, but couldn't make the grade at Stoke. Pulis paid around £2.25m to take him from the Madejski Stadium, but he played just 17 games in three seasons with the club before being released in the summer of 2011. With just one appearance in his final two seasons at the club, it's fair to say that Sonko was a huge mistake for Stoke.
