Ian Wright has backed Gareth Bale to have the same impact at Tottenham that Pierre-Emerick Aubameyang has had at Arsenal.

The Wales international is on the brink of a shock swap back to Spurs in a loan deal.

He is set to fly into London today and undergo a medical after the forward made returning to his former club a priority.

Jose Mourinho has also pushed hard for the deal, who has been a massive fan of Bale for many years.

And former Arsenal striker Wright believes the Welshman can be the difference in the battle for the top four.

"You have to say, if he can modify his game and play in that area up with the top three, him, Heung-min Son and Harry Kane – which sounds fantastic – then it’s going to be an unbelievable signing," Wright told Premier League Productions.

"You’re talking about somebody who is easily worth 15 or 20 goals, and how many points? 20 odd points? What’s that going to do for Spurs? Definitely going to be in the top four and challenging.

"And if you’re talking about the defence, with Reguilon and Matt Doherty, with that thrust that they’ve got – that’s what Harry Kane was missing."

When pressed on whether there are any issues over Bale's intensity levels after a lack of playing time, Wright added: "There has to be question marks.

"What people can’t get carried away with is: you’re not getting the Bale that left, obviously.

"You’re getting an older Bale, a more experienced Bale, but we’re still talking about a world-class Bale.

"If he can come back and get anywhere near what he used to do – though you’re not expecting him to hit that form – but at 31 if he can do anything there it’s going to be exciting for Tottenham.

"The amount of goals he’s scored that were winning goals for Spurs, the amount of games he won on his own for Spurs.

"When he left, at the time, for me he was easily one of the best players in the world."

Wright also went on to state how Bale can achieve the same sort of talismanic status Arsenal striker Aubameyang has at the Emirates.

"His ability is undoubted and the Spurs fans should be excited, simply because of the lift it will give them. It’s no different to what [Arsenal] have got with our talisman Pierre-Emerick Aubameyang.

"He was their main man and if he comes back and has any kind of impact like that, it’s not only going to give the fans a lift but the dressing room. I think it’s a dressing room that needs a lift as well.

"For him to come in, it will give the kind of boost that Tottenham really need at this stage of the season."
