Romelu Lukaku scored on his Inter Milan return on Wednesday in a 4-0 thumping of Viktoria Plzen to help his side make the Champions League last 16 and knock Barcelona out of the competition.

Belgium striker Lukaku netted Inter’s fourth with three minutes remaining and only four after replacing Lautaro Martinez, after Henrikh Mkhitaryan and an Edin Dzeko brace had already effectively ensured his team of at least second place in Group C.

Inter’s thumping win at a packed San Siro, Lukaku’s first appearance in two months following a thigh injury, has relegated Barca to the Europa League ahead of their match with Bayern Munich later on Wednesday.

Simone Inzaghi’s side are six points ahead of Barca and cannot be overtaken by the Catalans thanks to their better head-to-head record even if they beat group leaders Bayern.

“He’s come back with a crazy desire,” said Inzaghi of Lukaku.

“Tonight we knew we could make a dream come true if we look at draw for the group. I’m happy for the team, the club and the fan because having the San Siro that full so early is something special.”

Barca’s fate had already been almost sealed a fortnight ago when Inter drew a thrilling encounter at the Camp Nou 3-3, after a single-goal victory for Inter the previous week.

Xavi Hernandez’s Barca were favourites to go through with Bayern when the group stage draw was made, but they have won just one of their four fixtures and collected only four points.

Being knocked out so early is an embarrassment for Barca after a lavish summer spending spree and is also a further strain on their troubled accounts.

Barca was 1.3 billion euros ($1.28 billion) in debt before president Joan Laporta and the board pulled their infamous “palancas”, or financial leverage.

Meanwhile Inter’s qualification for the knockout stages of Europe’s top club competition continues a drastic upsurge in form for a team which looked deep in crisis at the start of the month.

Five wins from their last six matches in all competitions have made Inter one of a likely three Italian teams in November’s draw for the next round and have fans hoping of another Serie A title challenge.

Inter went for it straight from kick-off and they should have opened the scoring in the 25th minute when Jindrich Stanek made a smart double save.

First, Federico Dimarco shot straight at the Plzen goalkeeper when he could have rolled in Denzel Dumfries for a simple tap-in, and seconds later Stanek denied Mkhitaryan close-range header.

However Mkhitaryan would not be denied and 10 minutes later set Inter on their way, heading in Alessandro Bastoni’s deep cross completely unmarked while Dzeko occupied the Plzen defenders.

And Dzeko gave the hosts a commanding lead three minutes before the break, on hand to tap home a simple finish after Dimarco brilliantly brought down Nicolo Barella’s arrowed crossfield pass and rolled a pass across the goal from which the Bosnian could not miss.

Inter were not content to sit on their lead and after Lautaro Martinez’s low finish was kept out by the busy Stanek, Dzeko made completely sure of qualification in the 66th minute by rolling in his sixth of the season.

That left time for the return of fans favourite, Lukaku, and the cheers for his comeback had barely died down when he raised the roof with a deft near post finish following an exchange of passes with Joaquin Correa which capped a perfect evening. (AFP)
