Ashley Smith and his accomplice did not count on Kolasinac bravely fighting back, Harrow Crown Court heard on Friday.
WATCH - New footage of attempted robbery of Kolasinac and Ozil released
CCTV footage emerged of Kolasinac chasing away the two masked attackers in Hampstead, north-west London, on July 25.
Smith, 30, was jailed for 10 years after admitting to attempting to steal watches worth £200,000.
Judge Ian Bourne described Smith as a "career criminal" who was well known to police, and at the time of the attempted robbery he was out on licence for a 42-month sentence for burglary in 2017.

His accomplice, Jordan Northover, 26, also admitted to his role in the attempted robbery and will be sentenced at a later date.
Kolasinac and Ozil did not feature in Arsenal's Premier League opener back in August following the incident.
