Everton are reportedly braced for an improved bid from Manchester United for defender Leighton Baines this week.
United registered an offer of around £12m for the England international last month, which was swiftly rejected by the Toffees.
New Everton boss Roberto Martinez has held initial talks with Baines over a new contract, with further discussions over an extension expected this week.
Martinez values the left-back at around £20m and will rebuff any offer from United that falls below that mark, according to The Guardian.
The 28-year-old has spent six seasons on Merseyside, clocking up 246 appearances for Everton in all competitions.
