Adam Jackson notched a late consolation for the Sky Blues after a second-half collapse which saw them defeated for the second time this season...
Coventry City Under-21s' great run of form came to a halt at Millwall as the Sky Blues were beaten 4-1 at the Lions' training ground.
City were 1-0 down at the break and could have been level with a number of chances, but a second-half collapse saw the young Sky Blues defeated for just the second time this season.
After just seven minutes, the Sky Blues almost had the lead as George Thomas raced through one-on-one, but his low effort was well saved by Harry Girling.
The Lions then had the opener against the run of play two minutes later when Jack Powell headed in from close range from a corner from the right.
That didn't stop City's good period, when Ivor Lawton hit an effort inches over before Cian Harries curled a low free-kick narrowly wide from 20-yards.
Conor Thomas was the next to go close for the visitors, as he hit a firm 25-yard effort which had to parried away for a corner. From the resulting set-piece, Adam Jackson had an effort which was extremely well blocked by the defender in the six-yard box.
City couldn't find the crucial equaliser and Ryan Haynes forced another good stop out of Girling just after the break as he curled a free-kick from 25-yards out which the keeper clawed away.
Millwall eventually made the Sky Blues pay for not taking one of their chances as they capitalised on another set-piece in the 55th minute, this time Alfie Pavey slotted in from a corner at the back-post.
Five minutes later, City found themselves 3-0 down when Pavey notched his second after a good Millwall move down the left.
In contrast to City, the Lions made their period on top pay and they found the fourth goal on 62 minutes, when a high cross into the box was met by Jack Powell who found a finish from ten-yards out to end any hopes of a comeback.
Jackson had a late header cleared off the line but managed to grab a consolation with six minutes to play as Bassala Sambou headed down Haynes' corner which allowed the Boro loanee to poke in from close range.
The result was City's first defeat for four games.
