Colchester United have lost 5-0 against Ipswich Town
There was only one goal in it at half time, with James Norwood scoring from the spot after Cameron James fouled Danny Rowe.
Town scored early in the second half through Kayden Jackson, then Norwood notched twice to complete his hat-trick and Jackson added a fifth.
In the early stages, neither keeper was forced into making a save of any note, although Dean Gerken had to be out sharp to take a trhough ball ahead of Norwood in the second minute.
On eight minutes, the U's had their first attack of note, but a good block on the edge of the box prevented Jevani Brown's shot getting through.
The visitors opened the scoring on fifteen minutes, after Omar Sowunmi lost possession and Cameron James failed to take the ball as he slid in on Danny Rowe.
A penalty was awarded, and Norwood stepped up to put it just inside the post to make it 1-0.
Great play between Frank Nouble and Brown on the left almost created a real opening, but more good defending prevented Nouble getting a cross in.
El Mizouni should have done better seven minutes before the break, but screwed his shot well wide from the edge of the area.
The U's best chance of the half fell to Ben Stevenson on forty one minutes, but after a great turn, he struck his shot just over the bar.
Brown was replaced at half-time by fellow new signing Paris Cowan-Hall, but within ninety seconds of the restart the U's task got harder.
Andre Dozzell mishit his shot from close range, but Town sub Kayden Jackson was on hand at the far post to tap in to double the lead.
Nouble, who was playing against one of his former clubs, went close on fifty three minutes but hooked his effort just wide.
A mad ten minute spell completely took the game away from the U's, with Norwood completing his hat-trick and Jackson adding the fifth.
The first of the three, on sixty one minutes, saw Norwood cushion a header for himself before volleying home - then another volley at the far post by th eformer Tranmere forward made it four.
A flowing move down the U's right set up Jackson, but he still had to turn inside a defender and lift his effort high into the net.
A flurry of subs then upset the rythym of the game somewhat and whilst the U's couldn't get a consolation goal, the visitors couldn't add to their tally either.
The U's are at home again in their next pre-season fixture, with newly promoted Championship side Charlton Athletic vising the JobServe Community Stadium.
