Harry Redknapp has reiterated his desire to bolster Portsmouth's squad - but concedes he needs at least four new arrivals to avoid relegation. Redknapp will look to strengthen Pompey's squad during January, hoping to be buoyed by a positive result from Saturday's home match against Fulham - an early chance to get over Wednesday's 4-0 loss at Arsenal. "I have been given the chairman's backing," said Redknapp. "It is all going to happen. Watch this space. "I've got some targets in mind, certainly, and I'm looking at English targets mainly and looking to strengthen the team everywhere because it is such an unbalanced squad. "Look at us at Arsenal on Wednesday. There was no squad at all. "If a foreign possibility comes up we would consider it but it is no good us going to South America for somebody who has never played in the Premiership." With Vincent Pericard injured once more, Svetoslav Todorov still rusty after two years of knee problems and £1.2m signing Collins Mbesuma not even given a run in Redknapp's four matches so far, new strikers will be the priority. Redknapp has already been linked with Rangers' Peter Lovenkrands - a move denied by chairman Milan Mandaric - and Leeds frontman David Healy. But he insists: "We need four, five or six players. If I can get them I'm confident I can keep us up." Redknapp has softened his approach to chairman Mandaric's bid to sign Nigerian-born Poland international Emmanuel Olisadebe from Panathinaikos. Despite fears over Olisadebe's fitness, Redknapp said: "There is talk of maybe doing a pay-as-you-play deal and that is okay by me. "We have to be careful who we sign but if a player is not going to be paid when he's injured you cannot lose."
