Lorient coach Christian Gourcuff has demanded a major improvement from his players ahead of Saturday's Ligue 1 clash with Valenciennes at the Stade Yves Allainmat.
Gourcuff will not tolerate a repeat of his side's dismal 2-0 defeat at Guingamp last weekend which took their testing start this season to one win and two defeats from three games played.
Gourcuff's frustration was evident when he snapped: ``A lot of players had a very worrying level (against Guingamp). How do I fix it? I don't have a degree in psychology.''
Cameroon international striker Vincent Aboubakar is set to start against his former club, from whom he moved on a free transfer this summer.
Aboubakar said: ``It was difficult for me at Valenciennes and I wanted a change. The choice of Lorient was quickly justified and it is a very different philosophy which will help me develop my game.''
Valenciennes beat Toulouse 3-0 on the opening day but go to Lorient on the back of successive defeats against Bastia and Marseille in which late goals cost them dear.
Coach Daniel Sanchez said: ``We conceded in the 75th minute at Bastia and in the 85th minute against Marseille.
``I hope we will not make such big mistakes as we have in our last two matches. But it is a fact that it doesn't matter if these errors are made in the fifth minute - you have to focus right through.''
