Tottenham Hotspur are flying. Sitting third in the Premier League and off the back of an 11-game unbeaten run, Spurs have a genuine chance of finishing in the top three.
But whatever happens this season, the Lilywhites must add strength in depth this summer in order to mount a serious title challenge next season.
Here's a look at five players Andre Villas-Boas should try to sign when the window re-opens in July.
Gonzalo Higuain | Real Madrid
Recent reports have suggested a transfer tussle will take place between Tottenham and Arsenal for Higuain's signature, and it's obvious why.
The Real Madrid hit-man is renowned for his shooting ability and accuracy in front of goal. He has scored 100 goals in 180 La Liga games since joining Madrid in 2006.
Comfortable shooting with either foot and at 6ft tall, he can score goals with his head too.
He is currently fighting for a starting spot with Karim Benzema, but would surely be the main man at Spurs should a move come to fruition.
His experience in the big games would be of real benefit to Tottenham, as their squad lacks European experience at present.
Christian Eriksen | Ajax
Since the departures of Luka Modric and Rafael Van Der Vaart in the summer, Spurs have lacked some much needed creativity in the centre of the pitch.
The Lilywhites need somebody who can play a defence-splitting pass when the opposition get men behind the ball, and as it appears that both Xavi and Andres Iniesta will be unavailable, Eriksen will have to do!
The Danish playmaker has been gaining the attention of Europe's elite over the last few years thanks to his performances for Ajax. With 10 goals and 17 assists to his name already this term, Eriksen seems like a good option. He has fantastic technical ability and vision.
Spurs centre-back and former Ajax player Jan Vertonghen should be able to convince Eriksen to join him at White Hart Lane.
Leandro Damiao | Internacional
Surprise huh? No, of course not! It is one of footballs worst kept secrets that Tottenham Hotspurs are interested in the Brazilian forward, having had bids rejected in the past.
Despite Villas-Boas insisting Spurs will not move for Damiao again, I'm yet to be convinced.
Spurs need another striker for next season, especially if they are playing Champions League football. Jermain Defoe hasn't scored in 2013 and Emmanuel Adebayor doesn't look as though he wants to be there.
Damiao is just the type of striker suited to the 4-2-3-1 system AVB likes to play. With six goals in five appearances, he was also the top scorer at the 2012 Olympics.
James Forrest | Celtic
Okay, this one may actually be a surprise at first but let me convince you. Spurs are renowned for their danger down the flanks - Aaron Lennon and Gareth Bale are two of the quickest players in world football.
However, when one of them is missing, Spurs don't look like the same team. They lose the balance in the side and that energy on the counter attack. With Gareth Bale also adopting a more central role, another winger might be on the shopping list for Daniel Levy.
James Forrest is widely known as one of Scottish football's most talented youngsters. He is much more of the traditional winger, has fantastic pace and glides past defenders with ease.
His dribbling skills and calmness in the final third have elevated Forrest to becoming one of the most talked about youngsters in the game.
The financial state of Scottish football could also see Levy get him on the cheap, and we all know how Levy loves a good deal.
Roberto Soldado | Valencia
A third striker emphasises just how badly Tottenham need more firepower upfront.
Soldado may well prove to be the most costly on the list, having signed a contract extension with Valencia until 2017 just last year. However, Valencia lie 7th in La Liga and face a real fight for Champions League football, and Soldado might not wait around if they don't make it.
Valencia also have financial problems, which could force them into selling their priced asset.
Soldado has made a big impact in Spain's top flight this season, scoring 13 times.
Athletic, strong and deadly in front of goal, Soldado would be a real coup for Spurs if they can prize him away from Los Murciélagos. With Chelsea also rumoured to be interested, a transfer tussle could take place in England's capital.
Would these players suit Tottenham? Who do you think Spurs should sign? Have we missed anybody off the list? Tell us in the comments below!
