Michael David Demetriou (born 12 March 1990) is an English footballer who plays as a defender for EFL League Two club Crewe Alexandra.

[3][4] Demetriou began his career as a striker, playing for non-league sides Worthing and Bognor Regis Town.

He was then invited to join the Glenn Hoddle Academy in Spain, where he was converted into a defender, and had a spell playing for Jerez Industrial.

After departing Eastbourne, Demetriou signed a one-year contract with fellow Conference team Kidderminster Harriers on 20 June 2011.

[7] He made his debut on 24 September, filling in for Jamille Matt for the final five minutes of a 2–1 win over Mansfield Town at Field Mill.

[8] He got his first goal on 4 September 2012, a last-minute equaliser away to Braintree Town via a 20-yard strike called a "stunner" by the Essex Chronicle.

[17] Hours later, he made his debut, playing the entirety of a 0–2 home defeat to Dagenham & Redbridge in the first round of the Football League Trophy and was awarded 'Man of the Match' by the official sponsors, an award he went on to win again during a number of appearances and also making The Football League's 'Team of the day' on a few occasions during his time there.

Newport, who some deemed down and written off weeks previous, secured their safety from relegation on the last game of the season against Notts County to complete 'The Great Escape'.
