Pep Guardiola's disappointment at his team's 2-1 defeat by Arsenal in the FA Cup semi-finals on Sunday was compounded by the news that Sergio Aguero and David Silva may now miss the derby against Manchester United on Thursday through injury.
"We've let him down at times this season", Ramsey said.
Arsenal s third FA Cup final in the last four years - they won it in 2014 and 2015 - gives them a record 20 appearances in the showpiece match of the famous old competition.
"The system is adaptable, it is not a strict three at the back". They played long balls to (Olivier) Giroud, and used the counter attack with the quality of their players, set-pieces they are a tall team and they beat us.
With their form against the fellow Premier League giants a major cause for concern in 2016-17, Wenger says that his players overcame a tough challenge at Wembley.
And Sanchez came through for Arsenal in extra time, just as he did for the joint-record 12-time FA Cup winners in the 2015 semifinal, producing a victor in the 101st minute.
The Arsenal boss added: "Perhaps we've located a span where we wanted a little more security and [the system] helps with that".More news: May says Corbyn victory 'could happen' as she warns over voter complacency

"It was a very tight game but overall I think we deserved to win the game".
Next season we will be stronger.
After the game, he said to BBC Sport: "People have questioned us a lot recently".
"We need to keep the level of desire and hunger for every game of the season".
But in commending Sanchez's performance against City, Wenger vowed he'd at minimum see out his contract and hopefully expand his price.
Alexis' future continues to occupy space in the gossip columns of the European press but Arsene Wenger, speaking after the game, stated that the Chilean would remain at Arsenal for next season.
