Jamie Redknapp says Savio “lit up the place” on his Tottenham debut, but Roberto De Zerbi has challenged his latest signing to reach new heights after his stunning start to life at the club.

Savio, who joined the club on Tuesday in an £85m move from Manchester City, instantly made himself a fan favourite just over 24 hours after his arrival by scoring and grabbing an assist during a 20-minute cameo in Spurs’ 5-1 Carabao Cup win over Charlton.

The Brazilian brought excitement and flair with every touch, and despite only scoring once in the Premier League last season, showed some much-needed end product for a Tottenham team who netted just 48 times themselves.

His brilliant introduction earned praise from former Tottenham midfielder Redknapp, who claimed the 22-year-old was exactly the type of spark fans want at the club.

“He lit the place up,” Redknapp said post-match.

“This is what Tottenham want. Players like that who can get you off your seat. Who can cut inside and hit a ferocious left footed shot. He was excellent.”

However, despite making an immediate impression, Spurs boss De Zerbi challenged his new man to take the next step.

Prior to his debut, De Zerbi detailed what Savio needed to do to become one of the best wingers in the world, and doubled down on that after the game.

“Yes, it is a perfect day for him,” De Zerbi said of Savio.

“I think his biggest step and biggest improvement is to increase the number of goals because as qualities, I think he is one of the best wingers, but the best wingers score many goals.

“I spoke with him and we put the goal on 10 or 12 goals (target) because we need 10 or 12 goals from the wingers.

“Last season we suffered too much because also the number of goals were not enough to compete for nothing more than that (17th) position.”

Savio gives Spurs the hope their front line needs

Analysis from Sky Sports’ Callum Bishop:

“A lot can happen in just one minute of football. Even more can happen in 20. As we have just seen, that’s enough time to make yourself a cult hero.

“Savio’s arrival at Tottenham was shrouded in question marks. Why were Spurs willing to part with so much money for a player who managed just three goal contributions in the Premier League last season?

“Yet, the moment he stepped out onto the pitch in a white shirt, he was a livewire. Spurs fans value entertainment, and they were off their feet any time he got on the ball.

“The fact there was some end product that came with the excitement is even more important, especially for a Spurs side that have often been lacklustre in attack.

“The opponents will get tougher, and Savio will need to rise to that. However, as first outings go, having joined barely 24 hours ago, you can’t ask for much more.”

Chelsea are in talks to sign Atalanta defender Honest Ahanor.

The Blues expressed an interest in the 18-year-old Italian when they signed right-back Marco Palestra from the Serie A side in July.

BBC Sport has been told Atalanta are willing to sell Ahanor if their 40m euro (£34.3m) valuation is met.

Ahanor, who mainly plays at left-back, joined Atalanta from Genoa on a three-year deal last summer for a reported fee of 16m euros, plus 4m euros in add-ons.

He made 28 appearances in Serie A for Atalanta last season, establishing himself as a regular starter for the Italian club. He also made his Champions League debut in a 2-1 win against Club Brugge in September.

In May, he was called up by Italy for friendly matches against Luxembourg and Greece.

Chelsea manager Xabi Alonso has been building his squad since taking over at Stamford Bridge in July, signing England midfielder Morgan Rogers from Aston Villa for a club record £117m, and adding experienced Premier League players Danny Welbeck and Jordan Henderson.

Chelsea face Brighton at home in the Premier league on Sunday after beating Fulham 3-2 in their opening match of the season on Monday.
