Borussia Dortmund's director of sport Hans-Joachim Watzke said his side's 2-1 win over Fortuna Dusseldorf proved that there is not just one side in the Bundesliga with great strength in depth.
Dortmund coach Jurgen Klopp made 10 changes to the side which had beaten Real Madrid 4-1 in the Champions League last Wednesday, keeping only defender Mats Hummels in his starting XI on Saturday.
They were nevertheless too strong for Dusseldorf and cemented second place in the table, which they can clinch for certain next weekend.
"It has been said for weeks that there is only one club who can rotate and still win games," said Watzke.
"I'm very pleased that we have now done that successfully for a second time, just to show people that we also have players who can prove themselves in such a Bundesliga match.
"I am also very pleased that we got this result so that nobody can criticise us of playing only half-heartedly."
Nuri Sahin was one of the beneficiaries of the rotation, staking a claim for a place against his former club on Tuesday with a dream goal to set Dortmund on their way to victory.
He also set up the second for Jakub Blaszczykowski and praised the atmosphere within the club, in spite of the ongoing transfer speculation surrounding the likes of Hummels and Robert Lewandowski.
"It is no secret that we all have a very good relationship with each other," he said on his club's website.
"The lads here are simply sensational."
McClaren believes Terry's ability should be the major consideration if the Chelsea defender declares himself available to play for his country again.
It is understood the former captain is prepared to consider ending his international exile with the hope of going to the World Cup in Brazil in 2016.
Terry announced his retirement from the international game in September shortly before his personal hearing for a Football Association charge of racially abusing Anton Ferdinand.
The defender had appeared in court over the issue in July and been cleared, but an FA independent regulatory commission banned him for four matches and he was fined ?220,000.
That appeared to mark the end of his international career, but if he was to make himself eligible again, he could create a selection issue for England boss Roy Hodgson.
And while McClaren appreciates that there are political issues surrounding Terry, he believes any decision should come down to on-field concerns.
He told BBC Radio Five Live's Sportsweek programme: "You look at what's happened off the field, what's happened on the squad, internally what can happen, but also it's form as well.
"John Terry also is progressing in age and Chelsea are rotating him, so it's purely on form and Roy Hodgson looking ahead to the future.
"So if you look ahead to the future will John Terry in one, two, three, four years be involved in that?
"I think Roy Hodgson has a decision to make as to whether to go for the future or whether to win in the short term."
