Left sided defender or midfielder Robert Ullathorne was another successful product of Norwich City's youth team. He chose to join the Canaries despite schoolboy trials at Everton, Cambridge, West Ham and Luton. Robert also played for Kit Carson's PGL England team.

Robert made his first team debut on the 22nd of April 1991 away at Nottingham Forest. He went on to total 115 appearances for the Canaries over the next 5 years but was primarily a squad player making the most appearances (29) ironically in his last season with the club.

Out of contract at the end of the 1995/96 season, Robert was targeted by Crystal Palace but took opportunity of the Bosman ruling to make a move to Spanish Division Two side Ossuana. He returned to English football in February 1997 with a transfer to Leicester City that generated £100,000 for the Canaries. However he had played only eleven minutes of his debut against Wimbledon in the Coca Cola Cup semi-finals when he suffered a suspected broken ankle and was substituted. Allegedly he was unhappy at Leicester and sought a transfer despite regular spots in the Leicester first team. Robert had an impressive game for Leicester in the 1999 Worthington's Cup final where he kept David Ginola quiet. However Spurs won with a last minute goal depriving Robert of silverware. The breaking of his leg at Chelsea on 18th March 1999 raised real questions about his future as he might be thrown onto the soccer scrapheap.

Robert trained with Huddersfield in the week beginning 18th October according to the Sunday People (24th October 1999).
According to contributors on the bulletin board on the Official Norwich City website, Robert has had trials in the summer of 2000 with Spanish sides Real Zaragoza and Tenerife. In September 2000, he joined Newcastle on trial playing for them in reserve team matches against Blackburn and Leeds.

Robert joined Sheffield United on a short term contract at the end of November 2000. This was extended until the end of the season when he was then offered another one year contract. Failure to agree terms left Rob a free agent and in July 2001, he was linked with a prestigious move to Portuguese giants Benfica. His next destination was less glamourous - a trial with Barnsley in October 2001. At Christmastime 2001, Robert was linked with a move to Rob Newman's Southend which was denited by the Shrimpers. The following month saw the Football Transfers website link Robert with a move to Sweden and IFK Gothenberg.

Rob re-signed with Sheffield United and was part of their team that beat Norwich 3-2 on 7th September 2002. In October 2002, he needed a double hernia operation and did not appear again for the Blades that season. Following their play-off final defeat against Wolves, Neil Warnock has begun to reshape his squad for the forthcoming campaign and decided that Ullathorne was no longer required, along with Simon Tracey, Gary Kelly, Lewis Killeen, Ryan Mallon, Grant Smith and Tyrone Thompson

In October 2003, Rob trained with Stoke City to get match fit and win a new contract. During this time, he played for Stoke's reserve team. When this fell through, he spent a short while at Northampton before joining Walsall on trial, playing in the reserves versus Huddersfield during the second week of December 2003. The next club that he trialled with was Derby County in late January 2004.

On 20th February 2004, Rob signed a contact with Northampton until the end of the season. He will know the Cobbler's Director of Football who is John Deehan. He made his debut the following day in a 1-0 defeat at Scunthorpe. In June 2004, Rob rejected a new contract from the Cobblers to sign a two year contract with Gary Mills' Notts County. Although he made 37 starts in his first season at Meadow Lane, the 2005/6 season saw his form dwindle and his place taken by Liam Needham and Dan Martin. Rob was released by the Magpies in June 2006.

Rob then trialled with Kidderminster Harriers in July 2006. By the autumn he was playing for Goole Town in the Unibond Northern League First Division. He moved to Tamworth on 5th July 2007. However he quit the club at the end of August 2007 without playing a competitive game for them - stating that since he had not broken into the first team, he was going to retire and concentrate on a new career away from football.

Rob and his partner now run a lifestyle management company aimed at helping busy sportspeople organise their hectic lives.
