Spurs reportedly came very close to signing Joao Moutinho on the last day of the summer transfer window, but the disappointment of missing out on the Porto man has been somewhat lessened by the successful partnership that Dembele and Sandro have struck up in the centre of midfield.
If Spurs were to go back in for the Portugal midfielder, it may with the purpose of moving Dembele further up the pitch. But the Belgian's excellent form there, coupled with the imminent return of Scott Parker to add depth to the deeper central midfield slot, makes me think they should attempt to sign a more attacking midfielder in January.
Christian Eriksen is the man Villas-Boas should look to bring in. The outrageously talented Dane was the youngest player at the World Cup in 2010, and has continued to impress for Ajax since then.
He is still only 20, and has apparently been receiving rave reviews at Spurs from his former team mate Jan Vertonghen. Eriksen possess many of the skills that are valued in Spurs' current system, he is quick, comfortable on the ball and has a great range of passing. As such you could see him settling in well playing in front of the midfield pair, or even covering one of the wider forward positions.
Eriksen has said himself he is not thinking about a move at the moment, but if Ajax are eliminated from Europe early, which could well happen with their very hard group, the club may be open to a move in January for the right price.
If Spurs were to wait until next summer, there's every chance the competition for Eriksen will be too intense, especially if he continues to impress in the remainder of the season. If Spurs were to go for him, a January move might be the best option, and it could be an well-timed addition to the squad as it enters the second half of the season.
Villas-Boas has so far been very proactive in the transfer market, and Spurs picked up several quality players in the summer. Eriksen would follow the pattern of the other players brought in, and could turn out to be one of the best midfielders in Europe.
This January could be the North London club's last real shot at bringing him to White Hart Lane, and it might be worth making a real effort to do just that
