Smith said his side were superb in the win over Dundee United

Rangers manager Walter Smith hailed his side after the 3-1 win over Dundee United and said the SPL title was going to go right to the wire.

"It takes a huge effort for our team just now and I was glad to see the third goal go in," he told BBC Sport.

"Nacho's second goal was terrific and we needed some inspiration."

United appeared to be denied a penalty, but Smith said: "If we want to go over the season and look at the decisions we've had against us, that's fine."
