AS Monaco vice-president Vadim Vasilyev has invited Manchester United to bid for Djibril Sidibe.
Sidibe is being linked with United ahead of the summer market, with claims in France of contact having been made with his agents.
United boss Jose Mourinho sees Sidibe as potential cover for Antonio Valencia.
Asked about the rumours, Vasilyev encouraged Mourinho to step up his interest.
He told Telefoot: "Sidibé to Manchester United if we receive a good offer? Yes..."
