The midfielder admits Albion learned a harsh lesson after the Gunners repeated their 4-0 league win from earlier in the season with two goals in each half, although Simpkins felt her side played a lot better in their latest encounter.
She said, âThe biggest lesson from today is that you cannot switch off, especially as a midfielder. You have to concentrate against the top sides all the way through.
âItâs disappointing to lose. Weâre proud that we tried to implement everything in our game plan, as we showed desire and togetherness, but if we break the game down, the four goals could have been prevented.
"That being said, we have to recognise that we were playing against a really strong side, who are top of the table.â
Emily Simpkins chases down Kim Little.
Albion did beat the Gunners on penalties after a goalless draw in the Continental League Cup in November and, despite todayâs setback, Simpkins feels they are moving in the right direction.
âIâve been here two years and we do manage games better than we did when I arrived,â said the 29-year-old.
âAs someone who has been involved in both league games against them, there was definitely an improvement this time. In the first game we felt we got battered, but it wasnât like that today. Itâs just those fine margins â if you switch off against the top sides, then they will punish you.â
Emily Simpkins launches a pass up the pitch.
Albion are back in action on Wednesday when they travel to Manchester United in the quarter-final of the Continental Cup.
Simpkins added, âWeâll recover, but the good thing is weâve got another game coming up. Itâs all about the knockout stages now and weâre looking forward to it.â
