The 23-year-old defender won the competition five times with former club Arsenal, but even that is not enough to numb the pain of defeat to Everton in the 2010 Final.

Team-mates Katie Chapman and Eniola Aluko are among the others to have taken home a winner’s medal from an FA Cup Final with previous clubs.
But, as 2012 runners-up Chelsea continue the quest for their first-ever piece of silverware, Flaherty is determined to deliver.
"It’s the biggest game in the club’s history, and hopefully it’s going to be a great occasion but I don’t just want it to be a good occasion, I want to go there and win," said the 23-year-old defender.
"The fact we have it at Wembley shows how far we have come in the women’s game.
"I’ve been very fortunate to have been involved in many cup finals in my time and won a few, but I’ve also been on the losing side as well and I don’t want to do that again. That loss against Everton will certainly be driving me on when Saturday comes.
"The win against Bristol in 2013, the year after we lost against Chelsea in the semi-finals funnily enough, is probably my favourite FA Cup win, because a lot of people were against us."
A new FA Cup winner is certain to be crowned on Saturday, with Notts County having never reached The Final before.
Ellen White celebrates their Women's FA Cup semi-final victory over Everton earlier this season
County striker Ellen White, though, is another who will take to the Wembley turf having already experienced personal glory.
The 26-year-old England star has two FA Cup winners’ medals from her time with Arsenal, but believes the thought of lifting the trophy at the home of football would surpass that.
"I take a lot of pride in the two Cups I’ve won, but this will be extra special to play at Wembley, in front of a big crowd, a record crowd," said White.
"When you walk out at Wembley there are still bound to be a few nerves, but we can’t be frightened. It’s something a few of us got to experience in the World Cup and we have got to draw on what we experienced in Canada.
"It is going to be an incredible occasion, so it is important we put in a big performance and, come full-time, hopefully it will have topped the other two Finals.
"It’s an incredible feeling to now only be a few days away. We have had a lot of football to play between then and now, but it has been hard to keep it at the back of your mind, because it is such a big occasion for the football club."
