He never wore a Chelsea shirt in a competitive match, but in September 2010, Milan Lalkovic got a squad number.
The Slovakian winger was browsing the club website when he discovered that he had been included in a list of players aged 21 or under who were eligible to be called into Chelsea's senior squad during the 2010-11 Premier League season. His squad number, 64, was the highest the club had ever issued.
A quick, two-footed forward, Lalkovic was spotted by Chelsea while playing for Slovakia's under-15s. Chelsea nabbed him from beneath the noses of Manchester City in December 2006, with the teenager feigning illness as a pretext for missing a flight to Manchester and heading to London instead.
