The two sides were amongst a host of interested parties who attended England Under-21s' clash with Portugal on Tuesday.
The talented Portuguese beat England 2-1 to dump the home side out of the Under-21 championships and Premiership clubs have not been slow in recognising their talent.
The man who Spurs and Pompey were taking a particular interest in was central defender Bruno.
The commanding centre half is a Porto player, but he has been loaned out to Vitoria Guimares for the season - after spending the previous campaign with Farense.
It is thought that Porto will be willing to let the 21-year-old leave, which has alerted a number of clubs to his possible availability.
Portsmouth are already reported to have been out to Portugal to watch the youngster in action playing for Guimares, while Spurs are likely to know all about him from their own Portuguese starlet Helder Postiga - who played with Bruno on Tuesday.
A move for Bruno in January is a possibility for both, but they are most likely to wait until next summer when his loan spell finishes.
Also at the game watching the Portuguese were Bolton, Middlesbrough and Birmingham and together with Spurs and Pompey, they were keeping an eye on Jose Bosingwa.
The former Boavista star moved to Porto in the summer, shunning interest from both Boro and Newcastle United.
He is, though, struggling to hold down a regular first-team berth at Porto and may be tempted by England.
One thing against Bosingwa at the moment is that he is viewed as a versatile squad player.
Because of this he has been used in a plethora of positions for club and country, hence him being played at right back by the Under-21s - which came as a shock to many of the scouts at Goodison Park.
His role for Boavista was as a defensive midfielder and that is what any potential English employer is likely to see him as.
