Laczkó was a free agent and joined Olympiacos's pre-season training. Laczkó was given a trial period in which he played in two friendlies – one of which he scored in – and impressed Olympiacos coach Takis Lemonis enough to be rewarded with a contract with the club. On 25 July 2007, he signed a four-year deal with the club,[1] but was subsequently loaned out to fellow Super League side Levadiakos shortly after signing.
Loan to Leicester City
On 17 December 2007, Laczkó joined Leicester City on trial,[2] and he was signed on loan on 4 January 2008 for the remainder of the season, with the club having the option to buy him for a pre-determined fee.[3] Issued the number 32 shirt, both he and compatriot Gábor Bori (who joined the following week) were keen to earn permanent deals to stay at the club.[4] Laczkó made his debut in a 2–0 win over Coventry City on 12 January,[5] receiving a standing ovation from the home fans when substituted.[1] Then-manager Ian Holloway described him as "absolutely outstanding."[6] Laczkó made his only assist for the club against Norwich City on 16 February, setting up Stephen Clemence's goal in a 4–0 win.[7] He played a total of nine league games as Leicester were relegated at the end of the season; a permanent deal never took place.
Vasas
Laczkó returned to Hungary after failing to establish himself as a first team player with Olympiacos, signing for Vasas SC for whom he played for one season before joining Hungarian champions Debreceni VSC in August 2009.[8]
Debrecen
Laczkó played 35 matches and scored 2 goals in the Hungarian squad of Debreceni VSC. He played six matches in the group stages of the 2009–10 Champions League season with Debreceni VSC. He scored a double against arch-rival Diósgyőri VTK in the 2009–10 season. He won the Hungarian National Championship I with Debreceni VSC in 2010. He played and important role in the qualification of the 2010–11 Europa League season in the squad. He scored a goal against Litex in the play-off round. He also performed well against Sampdoria in the Stadio Luigi Ferraris, however Debreceni VSC lost 1–0. In the last round of the 2010–11 Europa League Debreceni VSC beat Sampdoria 2–0.
