Tottenham remain in the hunt for some notable names with the summer transfer window on the verge of closing.

Following the transfer of playmaker Luka Modric to Real Madrid, Andre Villas-Boas's squad have a void to fill in the midfield, and may need major reinforcements if they expect to qualify for a spot in the 2013-2014 Champions League.

Tottenham have already made their signing of midfielder Moussa Dembele official. The 25-year-old Belgian is believed to have cost Spurs £15 million.

Tottenham are also close to adding France's top goalkeeper Hugo Lloris. According to ESPN, the Lyon star is set to join Spurs for £12 million, and he could be joined be joined by Shakhtar Donetsk forward Willian. The Brazilian winger has been expected to leave the Ukranian club for several months.

The move to get Lloris is a sign that 41-year-old Brad Friedel may be either closing in on retirement or no longer fits into Villas-Boas's plans.

According to the Daily Mail, Spurs have made a loan offer to Barcelona for attacking midfielder Ibrahim Afellay. The 26-year-old Dutch star is also being pursued by Schalke and Arsenal.

But there are perhaps two bigger names that Spurs may add this week. Villas-Boas is looking to sign Joao Moutinho and Alan Dzagoev, according to the Daily Mirror. The duo would represent major additions to a squad that could use star power following the departure of Modric.

Moutinho is just 25 years old, and is known for his versatility and exceptional skill. Villas-Boas has long coveted the Porto star, who has 48 appearances with Portugal, and spent most of his career with Sporting. Moutinho has been valued between £20 million and £32 million. Several British publications have linked Moutinho to Tottenham this summer, and there doesn't appear to be many other suitors for him in recent weeks.

Dzagoev, 22, is considered one of the most promising midfielders in Europe. The Russian starlet had been linked to Tottenham for months, and the Daily Mail reported in July that his father said that a deal with Spurs was imminent. Dzagoev had been pursued by Arsenal and Manchester United, but neither club has shown much interest in recent weeks.

Dzagoev's contract with CSKA Moscow ends in December, and he is valued at roughly £12 million.

Meanwhile, Rafael van der Vaart continues to receive offers from Bundesliga clubs. The Daily Mail reported that Spurs received a £9 million offer from Hamburg, a club that Van Der Vaart formerly played with from 2005 to 2008.

Schalke had also been linked to the 29-year-old Dutch attacking midfielder for much of the summer, but there have not been any recent reports of the Bundesliga club making a bid.
