Despite their lowly league position and the huge number of issues facing Henrik Pedersen’s side off the field, the team had generally been competitive in their eight previous league matches.
Only a last-minute equaliser stopped them from claiming all three points at Birmingham on Tuesday, a result which would have seen them climb out of the relegation zone.
However, they were simply no match for Frank Lampard’s impressive Sky Blues.
There will be some question marks over his first but there was no doubting Thomas-Asante’s second after the protest-enforced hiatus. The former West Brom forward showed good feet to dance across the area before finishing sharply across Ethan Horvath after Dominic Iorfa had been caught in possession 20 yards from his own goal.
Wright’s ninth goal of the season should not have stood, with the striker clearly offside from Thomas’ knockdown from a free-kick but 3-0 at the break did not flatter the visitors.
With the game over as a contest Lampard made all five of his substitutions with more than 15 minutes of the game left to play.
Simms netted after coming off the bench for the second time this week and then Tatsuhiro, who had played a role in the fourth, got his first of the season and Coventry’s 27th from seven league games after the home side failed to clear a set piece.
Wednesday’s best chance to get on the scoresheet came with the last action of the match but George Brown headed over Barry Bannan’s inviting cross from close range.
The 5-0 result, which could have been more but for fine saves by Horvath from Ephron Mason-Clark and Sakamoto, matches Coventry’s biggest ever win over Sheffield Wednesday.
