Inter capitalised on poor results for two of their Scudetto rivals to extend their lead at the top of Serie A to eight points with a victory over Bologna on Saturday night.
Antonio Conte's men would have witnessed both Milan and Juventus drop crucial points earlier in the day in respective draws, meaning a victory at the Stadio Renato Dall'Ara could well seal a first title win since 2010.
Inevitably it was Romelu Lukaku who forced home the winner on the half-hour mark. He met a wonderful Alessandro Bastoni cross plumb on his forehead, and the hosts' goalkeeper Federico Ravaglia was unfortunate to see his fine save from the Belgian's header land back at the striker's feet, allowing him to literally tap home.
That was Lukaku's 20th league goal of the campaign, leaving him in some esteemed Nerazzuri company.
Roberto Soriano missed a gilt-edged chance for Bologna in added time at the end of the half, but Inter survived that scare to go in ahead at the break.
Five minutes into the second period Lautaro Martinez was unlucky to see his right-footed shot cannon off the woodwork before he was withdrawn shortly after.
Inter continued to toil and press in search of the second to make things comfortable, but the visitors struggled to create many clear-cut chances. The closest they came to doubling the advantage was a deflected Alexis Sanchez free kick that was tipped over the bar by Ravaglia.
The final quarter of an hour was punctuated by a number of niggly fouls and subsequent bookings for both sides, with tempers occasionally threatening to boil over.
However, Inter's lead was never really threatened and they will be satisfied with a one-goal victory that gives them a likely unassailable lead at the top of Serie A, with a game in hand over second-placed Milan.
