The ex-midfielder turned pundit has been discussing the West Ham icon.
Indeed, asked what the striker was really like at Upton Park, Sinclair took to Twitter to explain his thoughts on the controversial character.
And the fan favourite was 'a pleasure' for the ex-Hammer to play alongside, while he also helped out the younger players in particular.
For me Di Canio was a top man, gr8 pro who was superb for the younger players and a pleasure to play with https://t.co/vvz7s6O4py— Trevor Sinclair (@trevor8sinclair) October 24, 2015
West Ham fans will be pleased that many of the Hammers' current squad appear to share the same characteristics.
There is professionalism throughout the side and the likes of Mark Noble and co seem very keen to help out the young players.
Of course, the more controversial aspects of Di Canio's persona so far seem to be absent from this West Ham team. But there is plenty of the flair the Italian brought, demonstrated by the likes of Dimitri Payet and Manuel Lanzini.
With the east London side currently third in the Premier League table, Watford provide their next test. The Hornets beat Stoke City at the Britannia Stadium on Saturday afternoon and Slaven Bilic's men will visit Vicarage Road next weekend.
