Transfer News: Tottenham confirm signings of Ben Davies and Michel Vorm, while Gylfi Sigurdsson moves to Swansea
Tottenham signings of Swansea duo Ben Davies and Michel Vorm, with Gylfi Sigurdsson moving in the opposite direction.
Italian defender Davide Astori has signed a three-year contract extension with Serie A side Cagliari.
Seaborne has won three and drawn one of the four matches he has played in since making the temporary move to The Valley.
The 25-year-old was forced to sit out the final match of his original loan spell, last Saturday's 2-2 draw against Brighton.
But Seaborne will get the chance to extend his unbeaten run in the Charlton team after a fresh deal was struck.
