Wigan manager Roberto Martinez conceded that fan violence marred his side's FA Cup semi-final win over Millwall on Saturday.
Fighting broke out between Millwall fans during the match at Wembley, before Wigan went on to seal their place in the final after defeating the Championship side 2-0.
The Football Association have confirmed their intention to serve banning orders to all guilty parties involved, while police have announced that 10 arrests were made.
Fighting was solely restricted to the Millwall section of support, with many fans forced to flee for safety.
Martinez was quick to underline his side's impressive display in London, but admitted that the club's qualification to a maiden FA Cup final was soured by the incidents.
"It's a magnificent achievement, and it's a major statement too. (The players) have had a lot of derogatory comments, but they were incredible from start to finish," Martinez said.
On the violence, the Spaniard commented: "I didn't see it, but I heard there was a little bit of an incident.
"It's a shame, because the whole event was impeccable for both clubs.
"You don't want to see that in a football game. Normally it's a minority who leave a bad taste on what was a great semi-final."
Millwall counterpart Kenny Jackett was reluctant to comment on the rancour in the stands.
"I didn't see any fighting during the game, I wasn't aware of any problems," Jackett told reporters.
"I haven’t seen any TV footage, so I’ll have to examine the facts before I can form an opinion on it.
"It's not part of the game now and it never has been, but it's not something I can sum up right away to form my own opinion. I'm sure the evidence is there.
"We've worked very hard to do everything we possibly can to try to be trouble free, and we've had many high-profile games recently which have been absolutely fine."
