This past season proved to be a fantastic one for Rangers as they secured their return to the Scottish Premiership after a four-year absence.
They have also won the Petrofac Cup, and are looking to make it a triple success by winning the Scottish Cup against Hibernian this weekend.
Success in that final would see Rangers head back to Europe next season, and former Gers boss Smith says that would represent a great achievement for Warburton’s side.
“Given the period we have been through, you could never have imagined coming out of this season with a chance of getting into Europe," he told rangers.co.uk.
“Everyone still thinks we have a fair bit to go, and Mark Warburton himself will know that, but it would be a great achievement.”
European qualification would certainly represent a fine end to what has been a superb campaign for Rangers.
In fact, qualifying for Europe could be a huge boost to their plans for the summer transfer window too.
Warburton is keen to improve his squad and being able to offer European football would be a big boost to their hopes of securing their targets for next season.
Indeed, that could be key to their current pursuit of midfielder Joey Barton, with the Rangers boss already admitting his side cannot compete financially.
