Benfica midfielder Axel Witsel is being followed by Chelsea, according to the Blues' Brazilian star Ramires.
The 23-year-old Belgian international started both legs of the Portuguese side's Champions League quarter-final clash against the Premier League giants, and particularly impressed in last week's encounter at Stamford Bridge.
Ramires - who joined Chelsea from Benfica in August 2010 - believes Witsel could follow his example, and if he makes the move to west London, has no doubt the talented youngster will succeed in England.
"It's known when a player stands out that Chelsea are eyeing him," Ramires told the Portuguese media. "They're following Witsel and he's an excellent player.
"He's a player who can do very well in England."
Under the temporary charge of Roberto Di Matteo, the Blues have progressed to the Champions League semi-finals, where they face a tough test against current holders Barcelona.
In order to re-establish themselves as a powerhouse, both domestically and in Europe, Ramires has also identified a couple of other players that Russian owner Roman Abramovich should consider signing this summer.
"I would also recommend signing Maxi Pereira because he's also a great player," he continued.
"[Nicolas] Gaitan can [also] shine in English football. He's an excellent player, one of the best in the world."
