Chelsea have reportedly identified Wolverhampton Wanderers winger Adama Traore as a potential target for the summer.
The 25-year-old had a disappointing campaign for Wolves, registering only two goals and three assists from 37 league games.
He had to wait until April to score his first league goal of the season, but ended the campaign with a string of good performances.
Adama is one of the names on his shortlist. Tuchel believes the former Barcelona graduate would be a quality option for the wing-back role.
The Spaniard has two years remaining on his contract, and Wolves are likely to demand around £45m to sanction his departure.
He was linked with Liverpool last summer, but their interest has faded amid his inconsistent displays over the past 18 months.
Traore has made the Spain squad for the European Championships next month despite his unimpressive season with Wolves.
