It was a vital win for Coventry, who are reportedly close to finalising a deal to return to the Ricoh Arena next season.

They moved alongside Derby, six points above the bottom three.

Arguably, the visitors did not do enough to take anything from the game, struggling to create clear-cut chances while the Sky Blues looked the more dangerous.

Coventry, who had made two changes from the 2-1 home defeat to Middlesbrough in midweek, got off to a fine start.

Gustavo Hamer saw a free-kick saved after 10 minutes and shortly after Biamou capitalised on a misplaced Nathan Byrne pass before racing forward and slotting home.

The home side, with their tails up, went close to a second as Callum O'Hare released Fankaty Dabo on a marauding run down the right and his cross-shot was agonisingly missed by Biamou.

The visitors nearly had a way back into the game with a double chance in the 25th minute. Patrick Roberts saw a low shot deflected for a corner before Matt Clarke was denied by Ben Wilson.

Clarke saw a far-post header go wide while, at the other end, Leo Ostigard sent an effort over as Coventry went into the break with a slender advantage.

Both sides came out with plenty of endeavour after the break but found it hard to fashion clear chances.

The Rams' seven-goal top scorer Colin Kazim-Richards, who netted in a 1-1 draw against Coventry earlier this season, flashed a header wide.

But it was Coventry who went closest when a fierce drive from Matty James rattled against the post with Kelle Roos beaten.

Biamou could have had his second as he hit a well-struck effort wide after beating the offside trap while substitute Louie Watson blazed off target from distance as the visitors became more desperate.
