Ireland women's skipper Fiona Coghlan believes England will soon have to start looking over their shoulder as the gap between them and the rest of the RBS 6 Nations counties continues to close.
England have been dominant in their opening two games against Wales and Italy and have not conceded so much as a point to their championship rivals.
Their only defeat in the championship since 2005 came at the hands of Wales last year who secured a narrow 16-15 victory.
But Coghlan is convinced there are cracks starting to appear in the English armour and the other countries will be on hand to take full advantage when the opportunity arises.
She said: “England have so much money and backing at their disposal that they are always going to have an advantage over the other countries.
“We saw last year that they were beatable and all the teams go out there with extra passion against them.
“But England have such strength in depth that they will always be able to field a good side so the other teams have to be at their best to make a game of it.
“They are still in front of the rest of us but I feel it’s getting closer and hopefully soon we will all be able to compete at that level.”
