#4: CHELSEA
Antonio Conte was keen to offload Diego Costa in the summer. But, Atletico's transfer ban proved to be the biggest hurdle in the Spaniard's way back to his former club. The Blues have already acquired his countryman Alvaro Morata from Champions League winners Real Madrid.
With Lewandowski's departure looking imminent, Chelsea have been put on alert. According to reports, they are already in a race with rivals Manchester United for the Pole's signature. Lewandowski's arrival will definitely transform the Londoners into serious contenders for the Champions League title. Also, Lewandowski would be relieved of his pressure, considering competition with Spaniards Pedro and Morata., Lewy would certainly relish a chance to play in the Premier League.
Taking his age into consideration, Lewandowski might find an exciting challenge to prove himself in the world's toughest and most competitive league.
