Wadsworth says...
"It's been a bad week, we've lost a couple of players - Kissock and Baldacchino," he said.
"We've got so little variation just now, and this has been a poor day, but I'm not being critical of the players.
"Today is hopefully just a major blip in this run of games because we've done really well recently and we've still got two to play."
Wadsworth admitted a long journey was the last thing administration-hit Gretna wanted after a week when John-Paul Kissock returned to Everton and Ryan Baldacchino moved to Australia.
"Preparation wasn't great for the game," he added. "It was about 7-7:30 we were at the ground, we didn't stop for a meal and we had to eat on the bus, but the microwave wouldn't work. Cold lasagne - so the preparation was poor.
"I don't want to make excuses because I thought Inverness were terrific.
"Having said that, I thought the first goal was scandalous - it was at least three metres offside, it wasn't even marginal - but there's nothing we can do about that.
"I thought we might have had a penalty in the first half, which would have made it a better game."
Brewster says...
Craig Brewster is aiming for two more wins to secure Inverness Caledonian Thistle's best-ever points total in the Scottish Premier League.
"We have had a not too bad season," the manager told BBC Sport after the 6-1 hammering of Gretna on Saturday.
"If we win our next two games, we will probably have the most points we have ever had in the Premier League.
"Seven defeats on the bounce knocked us back. If we did not have that, who knows where we would have been?"
Brewster, whose side sit ninth, believes that he can improve their position next term.
"We are not far away and have a really good squad," he said.
"One or two will come in and one or two will leave, but I have to create a good environment for these guys to flourish."
Brewster was delighted the thrashing of the SPL's already-relegated side.
"It's always pleasing to score six goals with six different scorers," he said.
