Chelsea face stiff competition to sign Everton star Marouane Fellaini, with Real Madrid, Manchester City and Manchester United all considering a move for the midfielder.
The Blues were heavily linked to the Belgian international during the January transfer window and, according to reports in the Daily Mail, they might now face rival bids from Europe's elite should they make another move in the summer.
Fellaini was signed by Everton boss David Moyes for a club record £15million in 2008, and after five years at Goodison Park, it is believed the Belgian is keen to move in order to play Champions League football.
Everton have denied Fellaini's £75,000-a-week contract includes a £24m buy-out clause, but should the Toffees fail in their bid to finish inside the top four, expect bids within this region for the midfielder.
Fellaini would join a large Belgian contingent at Chelsea if he moved to Stamford Bridge, including Eden Hazard and loaned-out players Romelu Lukaku, Thibaut Courtois and Kevin de Bruyne. The Blues are among the favourites to capture Fellaini as they continue in their search for replacement for Frank Lampard, but Jose Mourinho, Roberto Mancini and Sir Alex Ferguson are all interested.
Since his move from Standard Liege, Fellaini has notched 31 goals in 162 appearance for the Toffees, while he has racked up 39 caps for Belgium, scoring five goals.
