Bohinen failed to win a regular place at Blackburn, but Smith believes he will be ideally suited to Derby's style of play.
"We've still got nearly a quarter of our season to go, and Lars could play a substantial part in us getting into Europe," Smith said. "Lars is a quality player who scores goals and he will be given a free role in a very offensive midfield position. I'm looking forward to working with him."
Bohinen's short-term aim is to earn a place in Norway's World Cup squad, but he insisted: "I haven't just come here for that. Of course, I'll do all I can to get back in the Norway team, but I'm excited about coming to Derby County."
Bobby Robson, the former England manager, is considering a move back to the Netherlands to take charge of PSV Eindhoven for the second time in his career. PSV, where Robson was manager from 1990 to 1992, guiding them to the league title twice, have offered Robson a deal reported to be worth up to pounds 15,000 a week.
The Dutch club are looking to fill the coaching vacancy left by the departure of Dick Advocaat, who is to take charge at Rangers next season.
A PSV spokesman confirmed that an offer had been made to Robson, who is currently director of football at Barcelona, following talks with the Dutch club's chairman, Harry van Raaij, in Spain.
However, the Dutch media believe Robson may be seen as a temporary solution and therefore only offered a one-year contract as the man PSV are said to really want - the former player and current Bruges coach Eric Gerets - will not be released from his existing contract until 1999.Reuse content
