Tottenham Hotspur will complete the £20m signing of West Bromwich Albion striker Saido Berahino before the end of the summer transfer window, according to former manager Harry Redknapp. The Baggies have already rejected two bids from the north London club for Berahino, who has also had a transfer request rebuffed by the Midlands side.

The Evening Standard understand that Spurs will make a third bid to sign Berahino on the final day of the window in an attempt to bolster their attacking options. Clinton Njie and Son Heung-Min have both arrived during the summer to support Harry Kane but there remains a perception that the club need further options to boost efforts to qualify for the Champions League.

Mauricio Pochettino's side have failed to score in two of their four league games this season and after the international break must balance domestic commitments with the start of their Europa League campaign, which will test their squad to breaking point. Redknapp feels Tottenham must add to their roster of strikers and says Berhaino could be signed for as little as £20m.

"The young players are improving but they still look short. Harry Kane needs help," he told Kicca. "They have not bought well and that is not down to the manager. The manager would have had no say in those players brought in before he arrived; they were brought in by other people. He has had to buy what he can and they're not good enough.

"The Bale money and the Modric money was badly spent and not well reinvested. I can't see them [Tottenham] making the top four again this year, it's a shame. I like the manager but he needs the tools and you can't just rely on Harry Kane to score the goals.

"I still think the boy from West Bromwich Albion will want to go there [Tottenham]. I think Tony [Pulis] will want to sell and I know he'd deny that but that is my honest opinion. I like the guy they have brought in [Salomon Rondon], I like Lambert so he has got strikers in.

"Berahino, what are you going to do with him? Tony plays one up front so I am sure they would like to get £20m for him. He is one of those kids with talent but he has to produce it over a period of time. He's had one or two problems off the pitch. I do see him going."
