By Wayne Veysey | Chief Correspondent Andre Villas-Boas is set to be appointed the new Tottenham manager on Monday.Sources have toldthat the Portuguese has accepted Spurs' job offer and the final paperwork on a three-year contract will be completed over the weekend.Barring any last-minute hitches, Tottenham are hoping to name Villas-Boas as Harry Redknapp's successor after Sunday's Euro 2012 final between Italy and Spain.The former Chelsea manager agreed to take over at White Hart Lane earlier this week, but official confirmation has been delayed until after July 1 due to contractual and legal reasons.Villas-Boas was initially Spurs' second choice behind France coach Laurent Blanc, but impressed chairman Daniel Levy with his vision for the future of the club during a series of talks throughout the second half of June.The 34-year-old is already actively engaged in the club's summer transfer plans and has approved proposed moves for Gylfi Sigurdsson and Jan Vertonghen as he looks to get Spurs back into the Champions League.Sigurdsson will be confirmed as Villas-Boas' first signing at White Hart Lane as early as Monday after he passed a medical and agreed personal terms with the north London club.Spurs have agreed an £8 million fee with Hoffenheim to steal the 22-year-old from under the noses of Liverpool after he snubbed the opportunity to re-join Brendan Rodgers.The new Liverpool manager wanted to take the midfielder with him from Swansea City, where he spent the second half of last season on loan.Sigurdsson will be working with an even younger coach than Rodgers after Villas-Boas convinced Levy that he has not been scarred by a dismal eight months in charge of Chelsea.After sacking Redknapp, the Spurs supremo prioritised a young, dynamic coach who can make full use of the club's new Enfield training ground and continue to overhaul a squad that is expected to soon be deprived of Luka Modric, who is edging closer to a move to Real Madrid.
