Second half display moves U's up to fifth.
Colchester United got back to winning ways on Saturday as a strong second half display saw them run out victors over Blackpool.
The U's were not at their best in the opening forty-five, but a tactical switch from boss John McGreal and a dominant second period helped them to victory.
The U's Head Coach had said earlier in the season that a good side doesn't lose two on the bounce and, on both occasions his side have been beaten this season, they've responded with all three points.
The visitors were the first to get on the scoresheet, as Gnanduillet shrugged off the attentions of Eastman and smacked home a low shot past Sam Walker.
The U's hadn't been able to get their game going in that opening period and looked like they might trail at the break, before that man Sammie Szmodics popped up with a third goal in three games eight minutes before the break.
The ball came in from Richard Brindley on the right and Szmodics took a touch, spun on the ball and lifted it home past Slocombe.
That got the U's tails up and they went into the break knowing they'd given themselves a chance of pushing on in the match.
And they started brightly in the second period, pinning in the visitors and getting a deserved goal ten minutes after the restart.
A corner into the box was helped over the keeper by the leap of substitute Tarique Fosu, and Porter was on hand to poke the ball into the net.
If that was a poacher's strike, his second goal was a classy finish from the U's front man with eight minutes to go.
He receiveed the ball and sent his defenders the wrong way with some superb footwork before finishing past the helpless Slocombe.
The U's number nine almost made it a hat-trick not long afterwards, again sending his defender the wrong way before pushing his shot agonisingly past the post.
U's games this season are never dull and the visitors gave themselves late hope as the impressive Brad Potts smacked home a low free kick just inside hte post.
But the U's had made good substitutions in the second half and the screening of Kamara and Slater ensured that they got home safely and moved back up to fifth in the table.
