Still and Yates have their sayThe Town entertain a Cheltenham side sitting pretty in second place in League 2 following an unbeaten start to the season.
The Robins were tipped to struggle this term after a disappointing 17th place finish last season, which came a year after they had reached the Play-Offs.
But after winning four and drawing two of their opening six matches they also arrive at Kenilworth Road on Saturday with the best defensive record in the division.
“I wish I knew!” exclaimed the Town boss when asked at his press conference why he thought Cheltenham had begun the campaign so well.
“They’ve had a good start. Sometimes teams start like that and carry on, others don’t. Sometimes it’s the other way round.
“They’ve found a way of playing and they’ve got some good players, and good players find a way of winning.
“Are they different team from last season? I don’t know. They didn’t have a great season last year.
“But they’ve got decent players who are performing well at the moment and that means I know it will be a tough game for us.”
Robins chief Mark Yates, who took over Whaddon Road in December 2009, admitted his team will need to be well prepared to get anything from their trip to Bedfordshire.
Talking to the Robins’ official YouTube channel, Yates said: “I think Luton will be a big player this season. They are a big club in the Football League.
“It was a brilliant appointment to get him [John Still] and he’s got a great record in this league with teams.
“You always know you’re in a game with John’s sides. They press you, they turn you; and at the moment they are playing some really, really good football.
“Although they’ve not had the results I think they’ve been really pleased with their performances and it’s a case of can they convert those into wins.
“We need to stop that and make sure that we’re as good as we have been for the last six games. Anything less means we get beat.
“Luton have got a lot of threats, a lot of good players and a crowd that really gets behind them.”
