(CNN) -- England striker Jermain Defoe has rejoined Tottenham after the north London club agreed a reported £15 million deal with Premier League rivals Portsmouth.
England striker Defoe will soon be back in a Tottenham shirt after agreeing a return from Portsmouth.
The 26-year-old Defoe, who left White Hart Lane less that a year ago, returns on what is believed to be a five-year contract.
"It's great to be back," the England striker told Sky Sports. "I'm looking forward to the challenge."
Defoe was paraded in front of fans ahead of Tuesday's 4-1 League Cup semifinal first leg win against Burnley after recently-appointed Spurs manager Harry Redknapp got his man.
"Personal terms have been agreed and the striker will undergo a medical," Tottenham confirmed in a Web site statement.
It was former Portsmouth boss Redknapp who snapped up Defoe from Spurs for around £8.5 million on deadline day last January.
Tottenham chairman Daniel Levy and Pompey chief executive Peter Storrie have been in talks over the weekend to negotiate a deal for Defoe's return.
The player, who has nine goals this campaign. has become disenchanted with life at Portsmouth since Redknapp quit the club two months ago.
"I wouldn't have sold him if I was manager at Portsmouth and Tottenham came back in," Redknapp said on Monday. "I'd be keeping him."
Ghana midfielder Stephen Appiah is on trial at Spurs this week and could sign until the end of the season while another Redknapp target determined to quit his current club is England winger Stewart Downing.
Downing delivered a transfer request -- later rejected -- at Middlesbrough on Monday.
Boro labelled Levy's initial offer for Downing "derisory" and chief executive Keith Lamb said on Monday: "We received a written transfer request from Stewart this morning. It was considered before being rejected.
"Prior to receiving the transfer request, we received an improved offer for Stewart from Tottenham.
"We immediately rejected this offer and informed Tottenham that Stewart Downing is not for sale and any further interest they have in the player will not be entertained."
Redknapp is anxious to strengthen his squad for the second part of the season, with the first-leg clash against Burnley highlighting his problems.
Benoit Assou-Ekotto and Jermaine Jenas are suspended, while Tom Huddlestone's ankle injury and Darren Bent's groin problem mean they joined defender Alan Hutton on the sidelines.
Zenit St Petersburg coach Dick Advocaat is resigned to losing star man Andrei Arshavin with Arsenal said to be looking a likely destination.
Arshavin has been a target for a number of Europe's top clubs since his excellent displays at Euro 2008 and it now looks as though the Gunners are stepping up their bid to take him to the Emirates Stadium.
Advocaat told PA Sport: "I am aware that Arsenal are interested but I don't know any more than that. However, I am expecting Arshavin to leave Zenit for another club.
"He is a top player and he could play for any team and any of the top teams in England, Arsenal, Manchester United, Chelsea or Liverpool.
"Arshavin played well for us last season but he didn't play as well as he can. There is still more to come from him and people will see that."
He added: "In principle, I have already bought Arshavin's successor, Danny, because I thought Arshavin was going to leave last year. Danny can play in the same position as Arshavin so we won't be disrupted when he goes."
Gunners boss Arsene Wenger has money to spend should he wish to strengthen the squad during the January transfer window - but maintains business will be done only for an "exceptional talent".
