Starting his career with Cambridge United, he would only play the one season before getting his move to the Premier League with Everton for a fee around £250,000. While at Everton Ruddy would go on loan a total of nine times but his most successful spell would be his last, moving up to Scotland with Motherwell.
Starting off as an initial 6-month loan in summer of 2009, Ruddy would take the first team spot in his stride, doing so well that he would extend his stay for the rest of the season.
Ruddy would finish the season with 15 clean sheets in 34 appearances with one of the highlights of this season coming in the second last game of the season, a 12 goal thriller against Hibernian at Fir Park. Hibs would go 6-2 up with Motherwell leaving it late with a 90+3 screamer from another Everton loanee Lukas Jutkiewicz.
After leaving Motherwell, Ruddy would move to Norwich to work under former Motherwell man Paul Lambert. In his first season with the canaries, he would become pivotal in Norwich’s promotion to the Premier League. Ruddy would also be voted Norwich’s Players Player of the Season in his first Premier League season keeping them in the league with a very respectable 12th place finish.
He would make his England debut against against Italy in a friendly in August 2012 after he was ruled out of Euro 2012 due to a broken finger but things worked out as he married his wife Laura on 2 June 2012. Prior to the Euro 2012 tournament, he jokingly cited breaking his finger as the reason he was able to have his wedding on that date.
Currently 34, Ruddy is backup keeper at Wolves but was key to helping them get back into the Premier League as he won the 17/18 Championship Golden Glove with 24 clean sheets and represented Wolves in the PFA Team of the Year. He was then replaced by Portugal goalkeeper Rui Patricio in their return to the Premier League.
