Paul Hurst was naturally disappointed with the 1-0 defeat to Braintree Town at Blundell Park on Tuesday night, and is challenging the players to respond at the weekend.
Speaking to Mariners PlayerHD after the game, he said: ''It was clearly disappointing. In some ways it wasn't surprising how the game was, it was clear that they came to frustrate. They managed to do that and gradually managed to suck the life out of us almost.
''We had a little go second half where you're hoping for something to drop but it didn't happen and you can clearly see why they've got the defensive record that they have.
In a game of few clear cut chances, Hurst was most disappointed that they managed to a nick a game that looked like it had a goalless draw written all over it for the majority of its duration.
''The frustrating thing for me is that they managed to nick the game as well because of a defensvie mistake from ourselves, '' said the Town boss.
''It's a bad goal to give away and its one of those games where there's very little for the crowd to get excited about.
''I do understand from the players point of view that it's hard to play against but you've got to make things happen and we didn't do that tonight..
''It was a totally different game from Saturday that was 0-0 where we had more than enough attempts to score.
''Tonight, there were very few attempts in truth and that's a large part in part to Braintree and how they set up. But at the same time, we have to try and find answers to that and the game is perhaps summed it up at the end when we hit the crossbar.
Hurst will now be looking for a response from his players when they head to Kent to take on third placed Dover Athletic at the weekend and has told his players to get their heads clear of this defeat ahead of that one.
He said: ''I think you can imagine that they're very, very down and disappointed.
''It's my job to try and pick them up again ahead of what is a very difficult game at Dover on Saturday so I've got some thinking to do ahead of the game and said to the players to get rested up, get their heads right and we'll go again.
''There's a slight of element of the team being written off and we need to use that. That's not everybody but there's clearly some frustration and I get that on an night like tonight.
''It was just flat in general from start of the game and we need to somehow find a spark about us to get the crowd involved, which we couldn't do.''
