Chelsea remain as the frontrunners to land Nathan despite interest from FC Porto.

The Blues have been heavily linked with the 19-year old midfielder who is almost certain to leave Atletico Paranaense for around £4.5million this summer.

Reports suggest that Portuguese giants Porto have joined the race for Nathan but the Daily Mail is confident that Chelsea will snap up the Brazil U20 international who was present as the Blues held Arsenal to a 0-0 draw at the Emirates Stadium on Sunday.
