Arsenal boss Arsene Wenger could yet stall their move for Borussia Dortmund striker Pierre-Emerick Aubameyang.
Aubameyang looks destined to leave the Bundesliga and north London has been touted as a likely destination.
But the Daily Star says Wenger has serious concerns about his temperament.
The French chief's reservations about Aubameyang's disciplinary record means he's only willing to cough up £35m for the striker.
But Dortmund, who rate Aubameyang at £53m, are determined to get maximum value for a player who's been prolific in the German top tier.
Aubameyang has scored an impressive 98 goals in 126 starts but has a long list of misdemeanours to his name.
