Everton have described a joint £28m bid from Manchester United for Marouane Fellaini and Leighton Baines as "derisory and insulting".
Not concerned
Martinez revealed last week: "
Marouane had a buy-out clause where it was very straightforward. If someone met that valuation, the club had no say.
"That finished on July 31 so you can imagine during that period everyone was a bit expectant about what would happen. Once that date went, you just focus on working for the next season.
"I'm not concerned at all at the moment (about players leaving).
"The window is open and until it closes you're going to get speculation, you're going to get a lot of talk, not just at Everton. It's the norm."
And the Everton boss also confirmed earlier this month that they had
received an offer for Baines, but insisted it fell well below their valuation.
He told the Liverpool Echo: "Before we went to Austria one club officially contacted ourselves with an offer, and it was a final offer.
"They put something over and the valuation wasn't anywhere near the quality of Leighton Baines.
"That was the end of it but since then, there's been all the speculation, which has been part of what the transfer window is.
"There's never been another club or anyone else putting in an offer for Leighton. Since then, we've moved on and we're continuing to focus on the start of the season."
