Florian Wirtz should follow Xabi Alonso's lead and reject interest from Europe's top clubs to stay at Bayer Leverkusen beyond this season, says former Germany international Carsten Ramelow.
Wirtz has been one of the standout performers in a remarkable campaign for Leverkusen, who are just one win away from clinching their first Bundesliga title.
The attacking midfielder has 18 goal involvements in 28 league outings this term (eight goals, 10 assists), with his latest goal coming from the penalty spot in Saturday's win over Union Berlin.
Among all Bundesliga players, Wirtz ranks third for successful dribbles (77), fifth for chances created (70) and fourth for expected assists (9.23 xA) this season.
His performances have won him plenty of admirers, with Liverpool, Manchester United, Manchester City and Real Madrid among those credited with an interest in the 20-year-old.
However, after seeing head coach Alonso reaffirm his commitment to Leverkusen, Ramelow, who made over 400 appearances for Die Werkself between 1995 and 2008, thinks Wirtz should follow suit.
"For Leverkusen, he is indispensable," the 2002 World Cup finalist told Stats Perform. "The same goes for the national team, where he has found a good role.
"There's a lot of speculation. When you're in great form, the big teams come knocking. Leverkusen hope he will continue with them for a while and move on after that.
"In my opinion, it would be good for his development to stay in Leverkusen, because you can see if young players leave too early, it is not always good."
With Alonso refusing to jump ship, Ramelow feels Leverkusen still have plenty to offer Wirtz, saying: "To show consistent performances, you have to be where you feel happy, and I think Leverkusen is a good place currently.
"They are so consistent. They have a lot of confidence and also a pinch of luck in the final moments to win games. That's really good. You have to look at the collective, the coach and his staff.
"But of course, Wirtz is a very young player who showed his talent many times over the last few years. He has made really good development and has lots more to come.
"Why not continue on that path for another one, two, maybe even three years and make the next step afterwards? This is what I think is the right way, but we will see what decision Wirtz takes."
Remarkably, Leverkusen are yet to lose a game in any competition this season. They have just six further games to navigate in the Bundesliga, while they will face second tier Kaiserslautern in May's DFB-Pokal final and are among the favourites to win the Europa League.
As Leverkusen look to banish the ghosts of 2001-02 – when they finished as runners up in the Bundesliga, DFB-Pokal and Champions League – Ramelow says all the credit lies with Alonso.
"When he arrived in Leverkusen, he was facing a few problems, which is normal. I think you have to give managers some time in this day and age," Ramelow said.
"That is what they did with him. He explained his philosophy and ideas very well to the team. The boys execute that really well.
"The whole package is in perfect harmony. The season they have played is phenomenal. Their streak is sensational and it looks like they will do this until the end.
"Every team has a bit of a lapse every season, but Leverkusen have been exceptional across all competitions. They can still win everything. Things are looking really good."
