Claude Pierre Marie Dielna (born 14 December 1987) was a French professional footballer who last played as a central centre-back for Ħamrun Spartans in Malta.

Born in Clichy-la-Garenne, Dielna started his career at Caen before moving to Lorient, where he signed his first professional contract in April 2007, which he described as his greatest sporting joy.

[12] Dielna went on to make 22 appearances for the club, though his spell was overshadowed by claims he fell out with manager Fabrizio Ravanelli.

[13] On 30 August 2014, Dielna signed a three-year deal with English championship side Sheffield Wednesday.

[18] His good display in the match earned him included Football League Team of the Week for the Championship.

[23][24] In his first season at Sheffield Wednesday, Dielna made twenty-five appearances and scoring three times in all competitions.

In the 2015–16 season, Dielna, however, found himself out of the first team, due to his own injury concern and was dropped out by new Manager Carlos Carvalhal.

[35] Although he suffered a muscle injury later in the season,[36] Dielna managed to regain his first team since his return and made seventeen appearances for the side.
