The north London club was hit by the passing of Ventrone, 61, last month after a short battle with illness.
In the aftermath, Spurs paid several tributes to the Italian including Harry Kane dedicating his winning goal against Brighton to the man dubbed ‘Marine’ as well as a permanent tribute at the Hotspur Way training ground.
On Friday, Ventrone’s son, Ivan, posted a touching gift sent by Dier, 28, to the coach’s family.
The player signed the England shirt he wore against Italy in September, his first Three Lions appearance in 18 months and one he attributed to the late Tottenham fitness coach.
“To the Ventrone family,” he wrote on the shirt.
“Gian Piero helped me to wear this shirt again. I will carry his values every day with me. Best wishes, Eric.”
Ivan Ventrone posted an image of the shirt on his Instagram account.
“I’ll forever be your supporter, just as my dad did,” he captioned the post.
