Johnson said: "We don't fear anyone going into the semi-finals.
"We're all focused on coming here and winning. We did really well in the qualifying campaign, and coming here Spain were probably the favourites.
"But we beat them 2-0 and so some people will say we're the favourites.
"If we are the favourites then I'm sure the lads will take it with a pinch of salt, and we just have to concentrate on keeping our heads down and looking towards the semi-finals."
