Katie McCabe is confident the Republic of Ireland have the belief and the quality to mount a serious push for World Cup qualification, but the Arsenal star warned they must learn from costly errors if they're to continue to improve.

Ireland rattled Olympic Games silver medallists Sweden on Thursday night with a disciplined and extremely hard-working performance. The visitors eked out a 1-0 win thanks to a Louise Quinn own goal but boss Vera Pauw was full of praise for her "tigers" in the aftermath.

McCabe felt the Girls in Green merited a point, however she's braced for an altogether different type of challenge on Tuesday when Ireland face a Finland side they will realistically be battling with for the runner-up spot in Group A.

The Finns already have six points on the board having won their first two qualifiers against Slovakia and Georgia.

"Finland is a totally different ball game," said McCabe.

"[Belief] is embedded in our team. We try to create that, especially in training. We know what we're good at but it's about eliminating the mistakes that kind of cost us in the end. We'll review it, recover and have full focus on Tuesday now.

"We've got real quality. We've got players playing at a high level.

"It was an unfortunate own goal but they are the fine margins at this level. We need to eliminate them."

Katie McCabe keeps tabs on Stina Blackstenius

Sweden boast two nominees for this year's Ballon d'Or Feminin - Stina Blackstenius and Magdalena Eriksson - as well as several players performing with some of Europe's top clubs. They are a polished, powerful team but Ireland made them graft for their victory at Tallaght Stadium.

"We stood toe to toe with them at times," McCabe stressed.

"They're the second best team in the world. They've got a lot of quality... they're really, really dangerous in those wide areas. That's why we settled in a 5-4-1 to get the extra body out wide. I felt we did that really well. We gifted them the own goal. We deserved at least a draw in my opinion.

"I'm disappointed for sure because I really thought we could have got that equaliser, especially in the second half. The belief from the girls, from minute one right through to the 96th minute, was fantastic. We left it all out there. We've come on leaps and bounds in the last few years."

One big concern for Ireland in the wake of the Swedish clash was an arm injury to Denise O'Sullivan that could rule her out of the game in Helsinki.

McCabe, airing her own concerns about her team-mate, added: "You know Denise, she runs herself into the ground for this team and represents Ireland to the utmost. The medical team will assess it hopefully prepare her for Tuesday."
