Massimo Maccarone's agent has cast doubt on the reported personal criticism by the former Middlesbrough player on Steve McClaren and Gareth Southgate.
The Italian has just ended an unhappy five-year stint on Teesside by joining Serie A outfit Siena on a free transfer.
Maccarone has been quoted, calling McClaren 'the most hypocritical and false person I have had the misfortune of meeting' and saying his training methods are 25 years out of date.
He adds that Southgate did not keep a promise to give him a run in the team when he took over as manager from McClaren.
Agent Paolo Fabbri told BBC Radio Five Live: 'He was not happy about the technical decisions of the manager but he is a polite person and he never used these words or expressions.
'He made the declaration in Italian, but it seems this has been made in the translation - as a kind of joke.
'He said his experience in England was not very happy because of the technical decisions of the managers Steve McClaren and Gareth Southgate. It was only the technical decisions, nothing more.
'He has expressed a concept, and it seems someone has been to work on that declaration.'
Maccarone was Boro's record signing when McClaren brought the striker to the Riverside in a £8.15million deal in 2002 - but the 27-year-old struggled to earn a regular starting place. In total, he made 102 appearances for the club - scoring 24 goals.
Maccarone was quoted by La Gazzetta dello Sport, saying: 'The `magnificent' McClaren is surely the most hypocritical and false person I have had the misfortune of meeting.
'He disgusted me by leaving me on the bench for the 2004 League Cup final after having told everyone I was his number one and he was counting on me.
'At the end, all he could do was mutter `I know, I know'.
'Only in England can someone with such evident limits become the head of the national team.'
He added: 'The training methods at Middlesbrough are a quarter of a century out of date.'
On Southgate, Maccarone claimed: 'When he was a player all he did was tell me I had to resist McClaren's mistreatment.
'He had promised me he would give me a run of six to eight games. He never kept it (the promise).
'Maybe that's the English way of doing things - but for me a promise is a promise.'
But on Boro supremo Steve Gibson, he insisted: 'He's the best chairman in the Premier League.'
