Sunderland manager Tony Mowbray is still waiting for his attack to fire this season after they ground out a goalless draw at Coventry.

Already without long-term casualty Ross Stewart, the Black Cats were also shorn of the injured Patrick Roberts, with Mowbray continuing to mend and make do with 17-year-old Jobe Bellingham leading the line.

Mowbray is hoping he will be able to bring in a striker before the transfer window closes on Friday in order to add a cutting edge to a side that frequently dominates possession.

In terms of chances created, it was Coventry who shaded matters and it required several good saves from Sunderland goalkeeper Anthony Patterson to preserve a point for the visitors.

Mowbray said: “The game panned out a little bit differently to what I thought.

“I thought we would come here and dominate possession, like we did last year against them, and they were good first half with the ball.

“I was disappointed at half-time and we readjusted a few things and I thought we were better in the second half.

“We got into some good positions and just the final ball wasn’t quite there today, as we can say in most of the games this season.

“The first three games we averaged 68 per cent possession and we got in behind teams so many times, but we couldn’t find the pass to put the ball into the back of the net.

“It was a bit like that in the second half today and yet you could always feel Coventry’s threat.

“They obviously played two strikers and a 10, they’re a menace and I thought the concentration was good defensively.”

The best chance of the first half came Coventry’s way after 44 minutes when Ellis Simms went through, only for Patterson to save well with his legs.

Sunderland looked bright after the restart and forced Ben Wilson into action twice in a matter of moments as he parried Dan Neil’s effort before also saving Dennis Cirkin’s follow-up.

Kasey Palmer then tried to force the issue for the hosts with a good run into the area, but his tame effort was comfortably saved by Patterson.

The clearest chance for either team to win it came in the 79th minute when Coventry debutant Yasin Ayari played in fellow substitute Haji Wright, who was also denied by the impressive Patterson.

Coventry boss Mark Robins said: “Across the backline, I thought we were outstanding.

“When we needed to, we threw bodies in front of it – I think Milan (Van Ewijk) has had his best game, Jay Dasilva has been really good today, Kyle McFadzean was a joke throwing himself in front of things.

“Then on the flip side of it, we’ve played some really good football.

“We got through them, we got into wide areas, they sat deep and tried to play on the counter-attack against us – they had three players there to try and break out at any given moment, and that’s why they’re dangerous.

“They dropped bodies in, we tried to open them up and if we don’t get it right because there’s no space, it means that as soon as we turn it over, they’re on a counter.

“That put us on the back foot in terms of coming out and being really aggressive.”
