RB Leipzig head coach Julian Nagelsmann compared Brian Brobbey to Inter star Romelu Lukaku after the Bundesliga side agreed to sign the Ajax sensation.

Brobbey will join Nagelsmann's Leipzig on a free transfer at the end of the season after agreeing a four-year deal until 2025.

Eredivisie giants Ajax were determined to keep Brobbey, but the 19-year-old Dutch forward opted to leave for Leipzig.

Brobbey, who made his senior debut for Ajax in October, has scored twice in seven substitute appearances in Eredivisie this season, while he has netted as many goals during the 2020-21 Europa League campaign.

Nagelsmann compared Brobbey to in-form Inter forward Lukaku after being asked about the similarities between the two players.

"It is always very tough for a player, when you compare him to others as people start to grow expectations that are not good for a player at that age," Nagelsmann told reporters ahead of Sunday's showdown with Eintracht Frankfurt.

"In regards to his physique and the way he plays, he is similar to Romelu Lukaku. And we would be happy if he can manage to become a player with the same qualities. But to paint a picture for the fans, you can definitely say that he is similar to Lukaku. But it is a great wish of ours that he can develop himself in a similar way and that he will be able to become as important for the European football [as Lukaku].

"If that will be the case, then our scouting department has made a great decision. We will cross our fingers for that to happen. But please don't start saying that he will play just like Lukaku, because this won't be the case."

After Friday's announcement, Brobbey said: "RB Leipzig is a great club and is playing an amazing season. Julian Nagelsmann is a young and very good coach, who I can learn a lot from.

"The team is stable and gives off a strong feeling of unity. I'm looking forward to joining the team and of course want to play my part in helping the club be so successful."

Leipzig are second in the Bundesliga, two points adrift of leaders and defending champions Bayern Munich through 24 rounds.

But Nagelsmann is unwilling to discuss the title race, adding: "I have already mentioned that I do not want to talk about that so much. Last year, we were a bit closer to Bayern or maybe a bit further ahead and we still didn't manage to win the tile and eventually fell behind with a few points difference.

"For us it is about following through with the consistency that we currently have. There are still many games to be played, many points to get but also many points to lose in either direction. We don't gain a lot from just talking about it. We need to try to be the best possible opponent for all the teams we face.

"It is our aim to win every match. I also said on Wednesday after [Champions League fixture against] Liverpool that I find it disrespectful against many others to say that the championship will be decided on the third of April. There are still a few games to go. This would also imply that we will win every game that we come up against. But to do so we will have to go to our limits. It's not like we will win every game with ease and then say: 'It was nice of you to come for a visit. Goodbye and it was obvious that you'll lose'. There's a lot of work to be done with many narrow games. We have seen it against Freiburg where we took a lot of time to find our rhythm needed to win the game.

"Against [Borussia] Gladbach, it took us until the 93rd minute to win. We had a bit of luck against Berlin as well, but have solved it with dominance towards the end and scored the very important second goal. It is not a walk in the park for us. Therefore, it doesn't help us to talk about the aim at the end. We have to be successful from game to game and take them as they come. Now it is Frankfurt and then we will see what will happen at the end.

"Of course, we are happy when coaches or experts are honouring our success but we can't gain anything from that. It is important that we deserve to be where we are after the 34th matchday. Whatever it will be, we will take that into our holiday. In the middle of the season, it is a nice feeling but it doesn’t help us a lot at the moment."

Leipzig's 53 points from 24 games represents their best-ever return at this stage of a Bundesliga season. The club's previous best was 49 points, achieved in both 2016-17 and 2019-20.

Meanwhile, Leipzig have won six consecutive Bundesliga games for the first time since 2019. Their club record stands at eight wins in a row from September to December 2016.
