Paulinho joined Tottenham Hotspur from Brazilian side Corinthians last summer, in a £17m deal as part of the summer spending spree which saw Spurs sign seven new players, but could be set to depart after just one season.
The 25-year-old has been a regular in his first season at Tottenham, but has struggled to live up to the expectations that the high transfer fee suggested.
Reports in Brazil claim that a potential move is being encouraged by Giuliano Bertolucci, the agent who oversaw Chelsea’s moves for David Luiz, Oscar and Ramires.
Despite failing to live up to the same sort of performances that he showcased in Brazil, Chelsea remain keen on the midfielder, but he has been ineffective several times this season.
Aerial duels remain a weakness for the Brazilian who has only won 23% of his headers this season with 13, a low figure considering he plays in the middle of the pitch.
He also struggles to break up the play, as he averages just 1.07 interceptions per game, which is substantially lower than other Brazilian midfielders in the league such as Fernandinho, Lucas Leiva and David Luiz.
Tackling is another area in which Paulinho has struggled to impress, averaging less than two tackles per game, and he is outclassed by the likes of Ramires, Lucas and Fernandinho in this category as well.
He has, though, managed to score five times in the Premier League this season, with two assists.
He was a key figure in Andre Villas-Boas’ side earlier in the season but has struggled to stay a regular in the Spurs side since Tim Sherwood took over in December.
With uncertainties continuing at Spurs as to who will be in charge next season, Chelsea will hope to get any deal for Paulinho done before he heads off to the World Cup in June.
Tottenham will look to get Romelu Lukaku from Chelsea in any deal that were to be completed, as the North London club are one of many admirers of the Belgian striker.
