Italy international Bastoni, 24, has become a fixture on the left side of Inter’s three-man central defence and played 46 times in an eventful campaign.
The Nigerian posted some impressive displays last season which played a key role in La Dea’s qualification for the UEFA Europa league.
Osimhen was on hand to ram home the leveller when, after a corner, Khvicha Kvaratskhelia’s low shot was blocked and fell to the clinical striker.
The Nigeria international who missed an entire month of action due to injury is currently top of the Serie A scoring charts with nine goals.
