Alonso has urged England fans to keep the faith, despite making it three consecutive losses with defeat to his Spain side on Saturday.
He said: “Yes, definitely, definitely. They are very good.
“They have very good conditions, quick, lots of quality, young players. I think Gareth and his team are doing a great job. We saw in the World Cup how well they did.
“Saturday also was a very tough game for us, but as I said we are very happy for the win."
