Alex Morris urged supporters to stick with his team after they lost in League Two for the first time this season.
The Railwaymen, down to 10 men from the 31st-minute mark, were beaten 3-0 at Salford City on Saturday.
The manager says he will shoulder the blame for the defeat, as he now prepares his side for the visit of Sutton United on Tuesday (7.45pm).
Morris said: “We’ve got two home games now and we will be going all out to get that momentum back.
“When we win, it’s on the players and they deserve the plaudits – I don’t want any pats on the back because that’s what we are there to do.
“When we lose, I take all the flak because it is on my head and I’m happy to take that
“But please stick with the players because we are coming through a transition period during which we need support. The fans are fantastic – they travelled in numbers again.”
The gaffer was disappointed with the result, especially after Crewe started brightly and almost hit the front through Dan Agyei.
But Conor McAleny broke the deadlock just before the half-hour mark, and Bassala Sambou was sent off shortly after it, to change the complexion of the fixture.
Morris added: “We started really brightly, exactly as we wanted to and the gameplan was working. We missed a great opportunity through Dan and we were in the position we wanted to be.
“It was a really soft goal to concede, they’d barely made any inroads into our half of the pitch up to that point, and the game completely changed.
“And then a player lost his discipline and the game changed again, making it 10 times more difficult to navigate. Days like this one, against an opposition which is really good in possession, in that heat, are difficult enough anyway. With 10 men, it was even more difficult.
“In the end they cruised to victory, we couldn’t get any pressure on the ball higher up the pitch. We conceded two more poor goals as the scoreline went further away from us.”
