Monaco vice-president Vadim Vasilyev criticised Manchester United and Chelsea over their lack of patience and care with Radamel Falcao.
Falcao, 30, endured two miserable seasons in the Premier League, first with United and then with Chelsea as he netted just five goals in all competitions.
The Colombia striker returned to Monaco for this season and has already struck twice in three games.
Vasilyev was unimpressed by how United and Chelsea treated Falcao, who he believes will return to his best.
