Aaron Pierre's strike with virtually the last kick of the game saw the Wanderers clinch a deserved draw in their opening pre-season match.Gareth Ainsworth's men competed every step of the way with their second-tier French counterparts, managed by former USA national coach Bob Bradley, and came closest to opening the deadlock in the opening exchanges when Adebayo Akinfenwa headed just wide from Myles Weston's cross.
Le Havre hit the woodwork before tempers boiled over when a home player sent Dayle Southwell to the ground with a fierce tackle which prompted a heated reaction from both sets of players. Akinfenwa's involvement saw him - and the offender from the French side - shown a red card, although the referee accepted both managers' request to continue playing with 11-a-side by bringing on a 'sub'.
The opening goal came during the hosts' best spell of the game having hit the bar with a looping shot not long before, but the Blues' substitute trialist keeper was beaten when a low cross from the left was converted smartly from six yards.
Aaron Pierre was then involved at both ends, chesting the ball down neatly for Garry Thompson to force a fine save from the keeper, before the defender dived in bravely to block what looked a certain goal as Le Havre looked to put the seal on their win.
But Pierre was to have the final say when he turned home a loose ball following Matt Bloomfield's corner, when Paris Cowan-Hall's header was superbly tipped away and the follow-up shot from a trialist midfielder was blocked.
