Redknapp is determined to bolster his attacking options during the transfer window after seeing Spurs miss out on Champions League despite finishing fourth last season.
Chelsea’s triumph in the competition meant they grabbed the final seat on Europe’s top table and the 65-year-old is keen to ensure the North London club secure qualification next year.
Toon striker Ba tops his shopping list after impressing for Alan Pardew’s men following his free transfer move from West Ham last summer banging in 16 goals as the Magpies finished fifth in the Premier League.
The Senegal international’s future at St James’ Park is far from certain though after Redknapp disclosed the existence of a £7 million release clause in his contract during an interview in January.
He is now hoping to exploit that by offering a makeweight in an attempt to tempt Newcastle into selling the 26-year-old just 12-months after signing him.
It’s reported that Defoe could be the player heading for Tyneside in a swap deal with Ba after it emerged he was keen to secure first team football away from White Hart Lane.
The 29-year-old England international played second fiddle to Emmanuel Adebayor for much of the campaign despite an admirable return of 17 goals in 38 all competitions.
It’s unclear whether Pardew would be willing to take the former West Ham and Portsmouth striker to the North East considering Newcastle’s transfer policy of targeting players under the age of 25.
Should a deal for Ba not come to fruition Redknapp is expected to push through a deal for Marseille striker Loic Remy who is rumoured to be keen to join the club.
The 25-year-old French international strikers representatives have already met with Spurs to discuss a £22 million move and he could become their first signing of the summer should talks end positively.
