Wicklow manager John Evans believes that London will pose a formidable challenge at home this year.
The Exiles are playing all their NFL games at McGovern Park this year and their manager Ciaran Deely has stated in the past that they want to make the Ruislip venue a fortress.
Carlow managed to come away with a win last weekend, but the fact that London managed to score two goals against a well drilled defence is a concern for Evans.
Last weekend, Wicklow began their campaign with a draw against Waterford and Evans is hoping that they can add to their points tally this Sunday afternoon.
"I think London is the only team in the last year and a half that have got two goals on Carlow because Carlow pride themselves on their defensive system," Evans told the Wicklow People.
"That's one thing we will be very wary of at the weekend."
