Manchester United are expected to return with separate offers for Marouane Fellaini and Leighton Baines, having incensed Everton with a joint £28m bid for David Moyes’s former players, The Guardian reports.

Everton described as "derisory and insulting" an offer that valued Fellaini at £16m, a decrease on what Moyes paid for the midfielder five years ago, and Baines at £12m, the sum rejected earlier in the summer. The offer was made late last week by United's executive vice-president Ed Woodward but sanctioned by Moyes, leaving Everton's chairman, Bill Kenwright, furious at the valuation and its potential disruption to Roberto Martínez's debut season at Goodison Park.

United's joint bid, as with their initial move for Baines in June, was rejected out of hand by Everton but is unlikely to be their last approach having failed to make any senior signings so far under Moyes. Everton are adamant the England left-back is not for sale and want to keep Fellaini, although an improved offer for the Belgium midfielder may test that resolve. United's prospects would therefore be improved by lodging separate bids for Everton's prize assets.
