The Premier League homegrown players rule explained and why Tottenham transfers are affected

The Tottenham fans are craving some transfer window action.

There are just two days of the summer window remaining and Spurs are the only Premier League side not to have made a signing so far.

Plenty have been linked with a move, but none have as yet come to fruition.

And the club are in no rush to cash in on players, as football.london revealed earlier this week, with the focus on bringing players into the club instead.

But as football.london has also revealed in this window, there are restrictions as to who they can bring into the club in the dying days of the window.

Spurs had problems last season with the number of foreign players they had in their squad.

At the start of the campaign, Vincent Janssen and Erik Lamela both had to be left out of the club's Champions League squad because there were no more spaces for foreign players. Only 17 non-locally trained players are allowed in that squad.

Then in January, Mauricio Pochettino told football.london that it was a "very painful" decision to have to tell young defender Juan Foyth that he would need to come out of that Champions League squad to fit new winter signing Lucas Moura in.
