Teams that enter the competition, which can provide a gateway to the UEFA Cup, are in the enviable position of being able to hit the ground running when the Premiership season start and are, by definition, probably the least ideal opponents for the opening match.
"I think Villa, to be honest, are going to be much sharper than us from playing in the Inter Toto Cup," admitted Glenn.
"The bottom line is, they’ve been playing what you would call real games and we haven’t. They are going to be really ahead of us in many ways and are probably the worst team we could be playing at the start of the season.
"Whether, in the latter period of the season they will struggle due to fatigue, I don’t know. We’re playing them first though and that is going to be an added difficulty, put it that way."
Facing a team in full flight is another reason why Glenn has been paying such attention to defensive detail since being disappointed with the goals conceded in the warm-up game at Portsmouth. An improvement was sought and achieved against Reading, Millwall and Fiorentina.
"Since Portsmouth we’ve been working on the defensive side and we looked a lot tighter and things we’ve been working on came to fruition. That’s pleasing.
"We’ve worked collectively in trying to win the ball. Up to Portsmouth, we hadn’t done any work defensively, hardly any at all. We did work with the back three, but not collectively."

The Inter-Toto Cup may be a much-maligned competition, but Glenn warns that Aston Villa’s participation in the tournament will see them arrive at the Lane on day one fully prepared and match-sharp.
