Reds player Declan O'Hara was dismissed before referee Brian Turkington ordered Patterson, who was just back from a long touchline ban, from the dugout.

"Everyone has seen a good game ruined. Glentoran, on their own, did not beat us," he said.

Cliftonville are expected to appeal the red card issued to Patterson.

A baseball was thrown at Patterson from the enclosure holding Glentoran fans as he made his way off the pitch.

The Solitude manager was in his second game back after serving a 14-match suspension.

"I've questioned myself in the past about being paranoid but I'm beyond that now," added Patterson.

"There was a sending off and cards were not issued to the other team.

"We've videoed the game and that will go to the Irish FA along with some comments made to our dugout.

"If we had kept 11 players on the park we would have won that game, without a doubt.

"We were under the cosh in the second half because the boys were tired.

"I've got in trouble in the past but I'm going to leave it to club officials this time."

Glentoran boss Alan McDonald was happy to reach his first final with the club but he was critcial of his team's finishing.

"Chances don't come along often against good teams like Cliftonville so you have to take those chances," said the former Northern Ireland captain.

"It would certainly have made it a bit easier for me in the last 10 minutes.

"Unfortunately, we didn't do that and that made it a bit difficult.

"All you need is for one person to slip or for there to be a little ricochet and it's all-square."
