Wales manager Gary Speed has said that Switzerland are the hardest team his side has faced in Euro 2012 qualifying after their 2-0 win in Swansea.

Goals from captain Aaron Ramsey and Gareth Bale have moved Speed's side up to fourth in Group G, with a potential final standing of third.

"I think Switzerland were the best team we've played and they caused us some problems," said Speed.

"In the second half there was a couple of decisions where we could have had a couple of penalties before we got one, and there was the sending off [of Switzerland's Reto Ziegler].

"So it went our way in that respect but the win was certainly deserved and well earned."

Wales conclude their qualifying fixtures with a trip to Bulgaria on Tuesday.
