Manager Derek Adams says the Shrimps must tighten up at the back and stop conceding goals if they are to stay in Sky Bet League One for another season.
The Shrimps were beaten 3-1 by Cheltenham Town at the Mazuma Stadium on Saturday, and Adams says the performance was a disappointing one.
“We need to be better defensively, I think we have been in recent games against Ipswich, Plymouth and Bolton, but we conceded really poor goals in the end," he explained.
“It is a really disappointing result, if you look at the goals from long throw-ins and a deflection in the first-half, it is disappointing as everyone knows, we know what the problem is all season, we have conceded too many goals.
“We have conceded 70 goals in the league, second worst in the league, we have to get better at that, we had some good chances in the game and we failed to capitalise on them."
Adams’ side head to Shrewsbury Town on Tuesday night looking to climb out of the drop zone, and the 46-year-old says he will have to assess his options after a few players picked up knocks in Saturday’s defeat.
He continued: "We are in the relegation zone for a reason and that reason is that we are conceding goals, we have to be solid and we have shown this season that we can score goals.
“We wanted the three points against Cheltenham and we weren’t good enough to get that, we have to go again on Tuesday night [against Shrewsbury Town] now.
“We will have to see what players we have available as a few players took knocks and we have to see if the players that were out can come back in for us, we will group tomorrow [Sunday] and see where we are at."
