The reigning Ligue 1 champions are set to pocket up to 140 million euros for Kylian Mbappe, as well as including Lucas Moura in the deal, the Brazilian joining Leonardo Jardim's side.
However, in the Prinicipality, they are looking for a striker to play alongside Radamel Falcao, and have shortlisted some options. They are not afraid to splash out...
Andrea Belotti
The Torino man impressed in the Serie A last season and was targeted by the likes of Chelsea and Manchester United. Monaco would have to trigger the Italian's £88 million release clause.
Diego Costa
As his dispute with Chelsea rumbles on, Diego Costa wants to leave Stamford Bridge. He would prefer a move to former club Atletico, but will settle for any team not managed by Antonio Conte.
Alexis Sanchez
A less-realistic option, but the French side would love to have him, according to French journalist Loic Tanzi. The Chilean is poised to stay put this summer, but Monaco certainly have the money to lure him in 12 months.
Kasper Dolberg
The 19-year-old Danish striker is one of the brightest young stars around. At Monaco, he would have the chance to grow after shining for Ajax last season.
Luciano Vietto
The Atletico man is being monitored by Monaco, who share a good relationship with Simeone's team. The Argentine doesn't count for his manager, but would be a great addition to Jardim's squad.
