HARRY Redknapp has bought Sean Davis, Pedro Mendes and Noe Pamarot from Tottenham to boost Portsmouth's Premiership survival bid.

Pompey boss Redknapp, who took over at Fratton Park last month, is understood to have paid £7million for the out-of-favour trio.

Mendes and Davis have struggled to establish themselves in a Spurs midfield containing Edgar Davids, Michael Carrick and Jermaine Jenas, while full-back Pamarot has only featured twice this season.

At the other end of the table, Liverpool have completed the signing of Denmark centre-back Daniel Agger from Brondby.

Agger, 21, has signed a four-and-a-half-year deal, and it is believed the fee of £5.8million is dependent on how many appearances he makes.

The belief is that the Dane will have to play 100 matches before the full figure is due.

Reds boss Rafael Benitez has also signed 19-year-old goalkeeper David Martin from Coca-Cola League One side MK Dons.

Martin spent a week on trial at Anfield before Christmas, playing in one reserve game, and Benitez was impressed enough to offer him a permanent deal.
