Chelsea sent scouts to Portugal to run the rule over Anderson Talisca ahead of a January swoop, according to reports.
However the Blues won't have it all their own way, with a host of clubs across Europe chasing the talented youngster's signature.
Talisca has been the subject of plenty of speculation in recent weeks, with the likes of Manchester United after him - indeed he could have already been a Premier League player were it not for work permit issues.
Chelsea boss Jose Mourinho revealed earlier this year: 'There were many English teams, great teams and important, that wanted him. Moreover, there were those who wanted to sign him, even though he could not play for now.
'They wanted to sign him, put him in a minor league [on loan] and hope that eventually he came to be selected [for Brazil's national team], and would consequently then get the work permit.'
Instead of either joining Chelsea or Manchester United he went to Benfica where he has continued to catch the eye which could well spark spark a transfer battle in the new year. According to O Jogo it is Chelsea who are most keen as things stand, and sent scouts to watch him action for Benfica's 3-0 win over Beleneses.
The paper adds that the Blues are considering a January bid. Scouts from Marseille and Hamburg amongst other clubs were present at the Stadium of Light, although it's not clear who they were there to watch.
Manchester United could well try and stop Chelsea - especially given his reputation as the new Yaya Toure. Boss Louis van Gaal could also try and lure him to Old Trafford in January. Liverpool, Manchester City and Arsenal have all been linked too.
