Per Mertesacker has praised his teammates' "fantastic achievement" after Arsenal reached their second FA Cup final in two seasons.
Two goals from Alexis Sanchez sealed an extra-time victory over a Reading side that pushed the Gunners all the way at Wembley.
It eventually took a blunder from the previously inspiring Adam Federici to break the Championship outfit.
A worry for Arsenal will be the injury that forced the German international off midway through the second half. Wenger will hope that the 30-year-old centre-back will be available for this Sunday's London derby against Chelsea.
But despite his injury, Mertesacker has revealed his delight after his side's triumph over the Royals.
“I twisted my ankle but obviously I am delighted that we are back at Wembley - that is a fantastic achievement for this group for the second consecutive time,” the vice-captain told Arsenal's official website. “We are really proud."
“It was a really tough game and we knew before that they would fight for their lives and give absolutely everything to keep us away from their goal and they did it fantastically. We are just delighted that we made it again," Mertesacker added.
Arsene Wenger will attempt to lift the trophy for a sixth time as Arsenal return to Wembley on May 30 to face Aston Villa, who overcame Liverpool 2-1 on Sunday.
And Mertesacker highlighted that an FA Cup victory would be a brilliant response to going out of the Champions League earlier this season.
“It is a little progress [and] it would be a great honour, back to back FA Cup wins. We were knocked out of the Champions League and that was a big blow for us but after that we responded and it is a great achievement. Let’s continue our great run," Mertesacker said.
Arsenal face Chelsea on Sunday and victory would cement their intention to finish in the top-two.
