Even at the age of 30, he will come with a hefty price tag.
Robert Lewandowski — prized possession of German giants Bayern Munich — has itchy feet.
He is flirting with the idea of playing in English football, toying with a move to the Premier League at the end of the season.
With 97 league goals in nearly four seasons at Bayern, plus another 74 in a similar timeframe at Borussia Dortmund, he has done his bit in the Bundesliga.
A fresh challenge is said to excite him. English football’s top clubs will be all over him from now on.
If Lewandowski can persuade Bayern to release him from a contract that runs to 2021 the scramble will be on. In the monied and frenzied modern era, this fella is a must-get.
There is a growing feeling this could be his last year in Germany.
His wife Anna was familiarising herself with London last week when she arrived on a shopping expedition — for clothes, not houses. Yet.
Bayern will not let go of him easily. At the centre of it is Pini Zahavi, the super- agent with links to some of English football’s biggest clubs.
Chelsea, inevitably, would be among the front-runners if Bayern reluctantly play ball.
By leaving Olivier Giroud and Alvaro Morata on the bench for the 1-1 Champions League draw at home to Barcelona on Tuesday, Antonio Conte made it clear he thinks the pair are short on quality. Lewandowski is an obvious upgrade on either of them.
There is the possibility of playing for Pep Guardiola again, working with the coach who signed him from Borussia Dortmund in 2014. At City, especially with Pep in charge, anything is possible.
Manchester United, pumping fortunes into the squad again to sign Alexis Sanchez in the January window, are another alternative.
The sense of history at Old Trafford, the glamour of pulling on the famous jersey and the chance to be Jose Mourinho’s main man is alluring for any top player.
Jurgen Klopp, head coach at Dortmund during Lewandowski’s four-year spell at Westfalenstadion, would have to be in the mix.
Liverpool, operating without an orthodox striker, would dearly love to have him.
This is the model No 9, a barnstorming centre-forward with the ability to score from any situation.
Poland’s captain has pedigree, consistently hitting the target during a career that took him to Bayern via prolific spells with Znicz Pruszkow, Lech Poznan and Dortmund.
Lewandowski guarantees goals — with two more coming in Bayern’s thumping 5-0 Champions League victory over Besiktas on Tuesday.
Bayern, under the wise old head of boss Jupp Heynckes, are relying on their main man to win the Champions League for the first time since 2012-13.
It is the jewel in the crown missing from Lewandowski’s trophy cabinet.
He wore Dortmund’s shirt when they reached the Wembley final in 2013, on the losing side when Arjen Robben charged through on goal to win it 2-1 in the 89th minute. A year later Lewandowski moved on a free to the Allianz Arena.
The German giants are already on notice, aware that their star striker is thinking about the challenges in English football.
They released a statement last summer, warning off potential suitors and reminding Lewandowski that he had only recently signed a new contract until 2021.
He is one of Bayern’s greatest strikers, in the company of Rainer Ohlhauser, Karl-Heinz Rummenigge and Gerd Muller after helping them to three successive Bundesliga titles.
There is room for one more before he makes a final decision on his future but the prospect of playing in England is back on the agenda.
Even when he turns 30 in August, Lewandowski will be a headline act.
