BBC Radio 5 Live's senior football correspondent John Murray says defensively Arsenal "have got a lot about them" but will have to go to one of the "toughest places" in their Champions League semi-final against Atletico Madrid.

Atletico edged past Barcelona 3-2 on aggregate to reach the semis, with the second leg playing out in front of a raucous home crowd at the Riyadh Air Metropolitano.

"When Arsenal played Atletico Madrid at home in the league phase they won 4-0 so that is not a bad one to have in your locker," Murray told BBC Radio 5 Live's Football Daily podcast.

"It's a totally different matter now at this end of the season, playing each other over two legs in a semi-final, but the second leg will be at the Emirates.

"The Metropolitano is right up there with the toughest places to go and they have shown that in an attacking sense this Atletico side have got a lot about them.

"There is a real good atmosphere and genuine noise inside that stadium. You have got to be on it there to perform against them.

"But in a defensive sense Arsenal have got a lot about them.

"Sporting are a capable team, Portuguese champions, and they could not find a way past David Raya in either leg. In this competition so far Arsenal have only conceded five goals in 12 matches.

"That shows you everything about their strengths."
