Inter continued their perfect start in the Champions League, cruising to a 4-0 win over Union Saint-Gilloise on Tuesday.

Lautaro Martinez continued his impressive goalscoring run, while Francesco Pio Esposito also played his part in two of the goals at Lotto Park.

It could have been a very different story, with Yann Sommer having to make a smothering save to deny Promise David with just over two minutes on the clock, with Christian Burgess seeing his effort blocked on the line by Martinez moments later.

Inter settled into the game, though, and found their breakthrough 41 minutes in, with Denzel Dumfries rifling into the roof of the net from close range after meeting Yann Bisseck's nod down from a corner.

Just five minutes later, Martinez got their second, latching onto Pio Esposito's squared pass to guide a low finish past Kjell Scherpen and into the back of the net.

That goal took the sting out of USG, with Inter dominating in the second half, and they were gifted their chance for a third goal as Kevin Mac Allister handled the ball during a challenge with Martinez. Hakan Calhanoglu confidently converted from 12 yards.

Pio Esposito then missed a golden chance to add another, bundling his effort from the edge of the six-yard box wide of an empty net.

But he did get their fourth in the 76th minute, sending a lovely low finish through Fedde Leysen's legs to net his first Champions League goal.

Data Debrief: Inter go big in Belgium

Inter have now won all three of their Champions League games this season without conceding a goal, the very first time they have done that in the competition's history.

And their 4-0 victory equals their largest margin of victory in Champions League history – they have only ever scored more in a 5-1 win over Valencia in October 2004.

Martinez scored his 24th goal in Europe's premier competition. He has netted 11 times in the Champions League in 2025, more than any other player in this period.

Inter actually underperformed their expected goals (xG) of 4.51 (21 shots), but showed their defensive solidity again, giving up just 0.95 xG to Union.
