Ruben Selles was given a shining glimpse of the work ahead if he's to keep Hull City in the Championship this season after another defensive horror-show gifted Coventry City all three points, with the Sky Blues coming from behind to win 2-1.

Despite being dominated for pretty much the entirety of the first period, City stunned the CBS Arena by taking the lead two minutes before the break when Ryan Longman headed Abu Kamara's cross against the bar. In the right place at the right time was Joao Pedro to guide in a controlled finish to give the away side the lead.

As was the case in midweek, City couldn't hold their lead for any significant amount of time, conceding a really poor goal just seven minutes into the second period when skipper Lewie Coyle lost Ephron Mason-Clark at the back post to score with his face. City had Ivor Pandur to thank for saving a second half penalty when Charlie Hughes gave away a foul inside the box, but shortly after, yet more haphazard defending allowed Jack Rudoni to head in from close range, and inflict a first defeat on the new head coach, who will have been left to scratch his head at some of the decision-making he saw from his side.

In the 50th competitive meeting between the pair, Selles named an unchanged starting XI from the draw with Watford in his first game in charge. The only changes came on the bench with Alfie Jones having recovered from the hamstring problem which kept him out of the last two games returning, and so too, Matty Jacob. Lampard made three changes with Luis Binks, Jay Dasilva and Victor Torp coming in.

City started confidently, winning a free-kick on the far side which Palmer sent into the box to McLoughlin at the back post, but the Irishman had strayed offside, so despite forcing a good low save from Brad Collins, the flag was up.

Despite a fair bit of early angst from their fans, the hosts threatened early on themselves with Victor Torp seeing a shot deflect over before Ephron Mason-Clark twice gave Lewie Coyle the slip to get into the box before finding Charlie Hughes and Sean McLoughlin equal to his threats.

The hosts were knocking on the door with Jack Rudoni fluffing a back post header when he could have gone with his foot, another lucky escape for the visitors, who were causing much of their early downfall with an error-strewn display.

Pandur went down inside his box to get some treatment, which allowed the Tigers players to come and get some instructions from Selles and his coaching staff, a move which didn't go down well with the home fans who made their feelings known to the referee, who later booked Pandur for time-wasting.

City were giving Coventry all the encouragement possible, with their sloppy passing and regular flow of mistakes. On the rare occasions they broke into the hosts' half, their attacks fell down with poor final passes and ultimately, bad decision making.

Their first shot of any kind came 39 minutes in when Alzate lofted a ball over the top for Kamara to run onto and fire at goal from a tight angle, though his effort lacked power.

In truth, City's biggest success of a disjointed, sloppy first period looked like getting to half-time at 0-0, until completely against the run of the first period, they stunned the home fans with the opening goal. Persistent play from Kamara outside the box eventually crossing for Longman, who, on the stretch angle, headed against the bar and in the right place at the right time was Joao Pedro to turn in from close range.

The striker was then booked, rather harshly, for a foul in added time at the end of the first period as City looked to see out what turned out to be little from the hosts by way of a response.

Selles made a change at the break with Mason Burstow coming on in place of Abu Kamara, and he almost fashioned a second for Pedro who couldn't get on the end of a cross, and moments later, City's defensive woes let them down again.

Torp's cross into the box wasn't dealt with by Coyle at the back post, having not been stopped by Giles, and the lively Mason-Clark bundled the ball into the back of the net just seven minutes into the second period out of nothing. Such a poor, poor goal to gift.

Just before the hour, Palmer came off to warm applause along with Giles, with Matty Jacob making his return and Marvin Mehlem on the pitch..

City almost regained the lead shortly after those changes with a quick break, Longman bending one towards the far corner, which was turned behind by the goalkeeper.

Coventry had a glorious chance to go in front with 25 minutes to go when Hughes' rash challenge brought down Bassette inside the box, moments after he was booked, but dressed all in pink, Pandur got him out of a hole, diving away to his left to save Torp's penalty kick.

Burstow was then inches away from giving City the lead in what had become a pulsating second half, angling a shot with the outside of his foot towards the far corner, Collins turning behind well.

The winning goal came from yet more poor defending, Mason-Clark skinning Coyle and Mehlem before clipping a teasing cross into the box for Rudoni to head in, their comeback complete.

Chris Bedia was thrown on for the final 15 minutes or so as City pushed for a way back into it, and with a couple of moments left, Burstow skied over the bar from the edge of the box.

Selles now has a clear week going into the Swansea home game, and the pressure on the Tigers to find a win from somewhere is growing massively.

Make no mistake about it, Selles has work to do, but he also needs better from his players because some of their decision-making left a lot to be desired, and this evidence shows there's a big job lying in wait.
