Fernandes could become the club's record signing

The 20-year-old midfielder has a groin injury which twice blocked a permanent move to the Fratton Park club.

Fernandes was eventually signed on loan from Benfica with a view to a club record �7m move.

Pompey physio Gary Sadler said: "Hopefully, without any setbacks, he will be involved with the first team by the end of the month."

Meanwhile, Portsmouth right-back Glen Johnson has returned to Chelsea - but only for treatment to his injured ankle.

He is also aiming to be fit for the home game against Bolton.
