Johansson provides the timely Finnish

The white wedding of a Charlton supporter in the centre circle at half-time might charitably be given as the reason for the home side's belated ringing of a few bells after being thoroughly outplayed. But, in truth, it needed a moment of pure genius from Jonatan Johansson to rescue a point three minutes from the end with his seventh goal in eight games.

The white wedding of a Charlton supporter in the centre circle at half-time might charitably be given as the reason for the home side's belated ringing of a few bells after being thoroughly outplayed. But, in truth, it needed a moment of pure genius from Jonatan Johansson to rescue a point three minutes from the end with his seventh goal in eight games.

Johansson, the Finn who faces England in a World Cup qualifier next week, seemed to have no chance when a ball from Chris Powell reached him with his back to goal as Charlton threw everyone forward. But without turning, he hooked it past himself, leaving even the excellent Magnus Hedman helpless. The loudspeaker introduction of Johansson before the match as "our new scoring sensation" was spot on.

In the first half, and much of the second, Charlton laboured against a slicker Coventry outfit who were uncompromising at the back, controlled and dominating in midfield and, given the chance, alert enough to test the excellence of Dean Kiely in the Charlton goal.

Had it not been for his foul temper, including an unpunished off-the-ball kick at Powell, Youssef Chippo would have been Coventry's outstanding player. He brought a desperate save from Kiely of a glorious drive from fully 30 yards in the first half, a minute or so after Richard Rufus blocked Craig Bellamy's shot as the Coventry striker skipped past Steve Brown and went round Kiely.

Coventry's merited lead came three minutes before the interval. John Aloisi, the notcher of a hat-trick in midweek against Preston and in his first Premiership start of the season, pushed a pass to Chippo, took the short return and won a violent tussle for possession with John Robinson before poking a mistimed shot which trickled just inside the post.

It would have been a lead of two goals a minute later had Kiely not plunged to his right to hold a Craig Bellamy shot after John Eustace's fine run.

Robinson, hurt in the goal tackle, only lasted a couple of minutes into the second half, by which time Johansson had already tested Hedman's agility.

The Finn was involved in the equaliser on the hour. Saving Bellamy's snap shot, Kiely sent Claus Jensen on his way. The Dane found Johansson, who beat Hedman only to hit the bar. Luckily, the rebound fell invitingly for Andy Hunt to head in just before he was withdrawn.

Coventry regained the lead with 20 minutes left. Climbing to clear Paul Telfer's corner, Rufus handled the ball. The penalty was instantly awarded and the defender booked, then Bellamy drove in the spot kick. Only Kiely's marvellous stop of Eustace's close-range volley kept Charlton in the game long enough for Johansson to maintain his scoring sequence.

Victory would have taken Charlton to third in the table but they were fortunate to rescue a point. The Coventry manager, Gordon Strachan, called his team's show "our best performance away from home this season, and we have won away three times". Enough said.
