Chris Coleman wants his players to use the international break to have a reality check and work out how to avoid a repeat of the dire display at Doncaster.
Coleman started the campaign with two straight wins.
But he has warned his players they face a battle in the other half of the table if they continue to dredge the same low levels they struck here.
Richie Wellens' wonder goal punished their lack lustre efforts and Coleman pulled no punches with his players, saying: "I warned them before the game that we wanted to sign off for the international break on a positive note, but I did not get that from them.
"It was great. We won our first two games and people were thinking here we go, but our target is 15 points from every 10 games. That won't get us in the play-offs, but it will put pressure on the boys in the play-offs.
"That is what we have to do if weare serious about doing that and being in the top half of the table. If we are not and we think we have arrived, we will be where we were last year."
Coventry won't be the first side to be found out by Sean O'Driscoll's passing addicts this season, but they could find no answers to the inventive angles and neat style of the side that are enjoying life at this level after last season's play-off victory over Leeds.
Wellens reckons Doncaster would be more at home in Spain's La Liga and the midfielder conjured up a goal that would have had the locals drooling in the Bernabeu.
Wellens' first of the seasonwasa30-yardspectacular that had Kieren Westwood grasping at fresh air and was the finishing touch to another display of the passing principles drilled into Doncaster by O'Driscoll.
"We are hardly all six footers.
We are all much smaller and we can only play that way. We are a bit like a Spanish team, we just pass the ball and keep passing it," said Wellens.
