Romelu Lukaku has revealed that he urged Kai Havertz to sign for Chelsea before the forward re-signed for the club.
Havertz arrived at Stamford Bridge for £70million last summer and now Lukaku has joined him.
The Blues forked out £97.5m to bring Lukaku back to west London after letting him leave in 2014.
That followed three difficult years as a youngster that saw him loaned out to West Bromwich Albion and eventual buyers Everton.
He would then go on to star for Manchester United and Inter Milan, where he scored 64 goals in 95 games as the Nerrazzurri side picked up the Italian title in May.
Now Lukaku is back at the Bridge and will be pleased to see Havertz in Thomas Tuchel's side.

The pair met in the Europa League last season as Inter beat Bayer Leverkusen 2-1 in the quarter-final.
In an interview with Chelsea's website, Lukaku revealed: "I spoke to Kai Havertz when we played against each other in the Europa League, and I told him to go to Chelsea, I don't know if he remembers that conversation."
Both attackers combining is a salivating prospect for Blues fans as Tuchel and co bid to lift a first Premier League title in five years this time around.
Lukaku has already spoken to his manager about the role he is expected to play having developed his game during his Serie A days.
"The conversation was really clear from him, that he wants me to be a presence and a leader in the team," said the 28-year-old.
"I have to just use all my abilities to make sure I can help the team as much as possible.
"My role will depend on what the game plan is and what the boss wants me to do. If he wants me to be a focal point or if he wants me to attack the spaces in behind, I can do it."
He added on his game after his time away from the Premier League: "The two years in Italy helped me master all the facets of the game for a striker and now I’m ready.
"I like the system that we play and I’m very flexible.
Where will Chelsea finish in the Premier League this season? Give us your predication here.
"I can play as a two or by myself and I’m used to the system because it’s what we play with the Belgian national team so I don’t need much time to adapt.
"It’s just knowing the strengths of my team-mates in important positions and knowing what we do off the ball, then I can do the rest."
And the Lukaku who left for Everton on a permanent basis seven years ago is a very different striker to the one of today.
"I just feel more complete. I’ve tried to master all the facets that a striker needs and I just want to keep improving on the small details all the time and keep improving on my strengths as well," explained the Belgium international.
"I just want to try to help the team win and be available for the manager as well as for my team-mates.
Lukaku affirmed: "I want to make sure that they feel comfortable and they can lean on me in whatever situation we’re in."
