AC Milan striker Zlatan Ibrahimovic says rivals Inter Milan would suffer if they let Samuel Eto'o leave.
The Cameroon striker is the subject of intense transfer speculation over a possible big-money switch to Russia to join Anzhi Makhachkala.
Intriguingly, the 30-year-old says he could also move to England.
And having let Ibrahimovic himself leave two years ago and Mario Balotelli last year, the big Swede says Inter would be ill-advised to lose Eto'o.
"If Inter lose Eto'o it's normal that they'll lose quality, there isn't another player like Eto'o, he's proved he's one of the best in the world," Ibrahimovic said.
But the Swede admitted he does not know how he would react if a team offered him the kind of money being pushed under Eto'o's nose.
"I'm happy to stay at Milan and so I'd say that I wouldn't accept.
"However, it's one thing to talk, you have to see. It's not easy, I haven't been offered anything and I hope it stays that way."
Eto'o is reported to have been offered US$30m a season to join the Dagestani outfit on a three-year contarct.
Ibrahimovic was himself involved in a huge transfer that saw him leave Inter for Barcelona and Eto'o head in the opposite direction.
However, after one year in Spain, Ibrahimovic came back to Milan to join the red half of the city where he won the Serie A title in his first season.
He has never won the Champions League, unlike Eto'o who has won it three times.
