UEFA has opened an investigation after Inter supporters were denied entry to Tuesday's Champions League tie with Porto despite having tickets for the match.
Footage emerged on social media ahead of the last-16 second leg showing hundreds of fans queueing to get into Estadio do Dragao as the game kicked off.
Porto had announced earlier in the day that Inter spectators who had purchased tickets in the home end, even if through the club, would be turned away.
But Inter claim an agreement was reached for their fans to attend the game if they wore neutral colours.
European football governing body UEFA confirmed on Wednesday that the matter is being looked into.
“UEFA had been made aware that a large contingent of visiting supporters had procured tickets in home sectors of the stadium," a spokesperson said.
"The UEFA regulations stipulate that five per cent of the stadium capacity must be provided to the visiting team in a segregated area for their supporters.
"The responsibility for the safe and secure management of spectators and the associated ticketing policy are determined by the match organiser and the relevant authorities.
"Mitigation measures were discussed between both clubs. UEFA is currently looking into the matter."
Inter claimed a goalless draw to advance through to the Champions League quarter-finals as 1-0 aggregate winners.
The Italian club's chief executive Beppe Marotta dedicated the result to those who were unable to get into the ground.
"We celebrate this passage that Inter had not achieved for 12 years, we give the credit to our coach, our players and the fans who were present," he told Sky Italia.
"I also want to spare a thought for circa a thousand fans who were left outside the stadium even after regularly purchasing a ticket.
"I saw footage of families who were locked outside, children crying who had flown here from Italy.
"Football must represent unity and joy, so this is a bitter page in what was otherwise a wonderful evening.
"We had met with the local authorities this morning and they assured us the fans would be allowed in even beyond those limits of the away section. Instead, this did not happen.
"These were for the most part families with children, who certainly weren't here to perpetrate acts of violence, but to support their team.
"I don't believe the situation was so serious as to ban their entry.
"We realise UEFA are not to blame, but we feel that with a formal complaint we can prevent this sort of thing ever happening again."
Mallorca 0-1 Atletico Madrid: Early Riquelme strike earns narrow win
Atletico Madrid closed in on a Champions League spot after winger Rodrigo Riquelme's early strike earned his side a 1-0 win at Mallorca in LaLiga on Saturday.
With four games remaining, Diego Simeone's side are fourth in the standings on 67 points, six ahead of fifth-placed Athletic Bilbao, who beat Getafe on Friday.
There was an end-of-the-season feel at a half-empty Son Moix stadium with both teams lacking urgency in a lacklustre match, with the only standout moment being Riquelme's fine individual effort in the fifth minute, which ultimately secured the win for the visitors.
Riquelme pounced on a loose ball in the edge of the box and cleared two defenders before unleashing an unstoppable strike just inside the right post.
Data Debrief: Mallorca's blunt attack easily stopped
Mallorca mustered an expected goals of just 0.24 in this game, and they have now failed to score in 15 of their 34 league games this season. Only Cadiz (17) have failed to score more often in the competition this term.
That is despite the hosts having attempted 526 passes in this game, their highest total in a single league match this season.
Sassuolo 1-0 Inter: Serie A champions suffer surprise defeat
Inter suffered only their second defeat in Serie A this season as a first-half goal by Armand Lauriente gave relegation-threatened Sassuolo a crucial 1-0 victory.
Sassuolo have a unique hold over Simone Inzaghi's side this season, as the only team to beat Inter in the league, having secured a 2-1 victory in the reverse fixture in September.
The result was a big boost in Sassuolo's battle against relegation, as they sit second from bottom on 29 points, with only three points between them and Cagliari in 14th place.
Lauriente got the only goal of the match after 20 minutes when Josh Doig managed to wrestle the ball back from Denzel Dumfries near the corner flag and pulled it back, with Sassuolo's matchwinner on hand to slot into the net from close range.
Data Debrief: Long time coming
This was the first time Inter have lost a league match against a team in the bottom two of the standings since way back in November 2014. On that occasion, they went down 2-0 to Parma.
Lauriente, meanwhile, has scored four Serie A goals since the beginning of April, a joint-record in the period in the top-flight (level with Hakan Calhanoglu).
Xavi insists there is 'no debate' over his Barcelona future
Xavi insisted there is "no debate" over his future at Barcelona after the Blaugrana's title hopes were dashed by Girona.
Barca lost 4-2 to Girona on Saturday, ensuring Real Madrid were crowned LaLiga champions.
Xavi, having initially elected to leave the club at the end of the season, last month performed a U-turn on that decision, confirming he would stay on until at least the end of the 2024-25 campaign.
Yet that did not stop the Barca coach facing questions over his role in Saturday's post-match news conference.
"There is no debate over my future," Xavi told reporters, before expanding on his feelings after the defeat.
"I am sad, disappointed. We have experienced both sides of the coin. Ineffectiveness have killed us once and again.
"I'm the first to be angry, to be p***** off with this situation, I understand the fans. Before being a coach, I was a fan. I understand our people's frustration."
Barca are now in third place and, with four matches remaining, must now rely on Girona slipping up if they are to have any chance of contesting the Supercopa de Espana next season, with a trophyless campaign guaranteed this time around.
Girona, on the other hand, sealed Champions League qualification for the first time in their history.
Portu came off the bench to score twice in Saturday's win, and he gave an emotional interview in the wake of the victory.
"It's incredible to look at your shirt and experience this. There is nothing more beautiful than living this," Portu told DAZN with tears rolling down his face.
"I had a thorn in my side with this club. A few years ago, I experienced the other side, which was relegation and I felt very responsible because I played a lot. Today I made amends with the fans and I can smile again."
