Phil Jagielka accepts Everton could be forced to sell key midfielder Marouane Fellaini this summer - if the price is right.
The 24-year-old Belgium midfielder arrived at Goodison Park in a £16million move from Standard Liege in 2008 and has been a vital performer for the Toffees.
Jagielka knows how crucial Fellaini is to the team but with the financial realities of life at Everton mean he is realistic about the club's chances of keeping him.
He said: "Unfortunately, with the way the club is, if somebody comes in with a £20million-plus offer, the chances are he's going to be sold.
"We love Felli and we'd love him to stay. There's not been that much transfer talk but we know the situation we're in.
"We bought him for £16 million and I don't think the club would take a loss.
"He's developed in that time, especially in the last few games of the season, just behind the front one, and he's destroyed teams."
Jagielka was impressed with the performance of Fellaini when in action for England against Belgium in Saturday's friendly international at Wembley.
Jagielka added: "In terms of marking Felli, he's faster than I remember. He must have put a yard on. I can't stop laughing when I see him and it's not just his hair.
"He's a fantastic player. Belgium have got a few players for the future and, once they kick, on they'll be a team to watch."
Jagielka has seen players leave Everton before, with Joleon Lescott a notable example having left for Manchester City in acrimonious circumstances in 2009.
But he was grateful for the presence of his former team-mate on Saturday.
The pair were reunited against Belgium after John Terry and Gary Cahill were both substituted through injury, allowing Jagielka to earn another England cap.
The 29-year-old is relishing the prospect of his first tournament at Euro 2012 and admits to feeling comfortable alongside former Everton team-mate Joleon Lescott.
He added: "Gary went down early and we made one defensive substitution so I wasn't expecting to get on but JT (Terry) had a little niggle so it was nice to get another cap.
"Myself and Joleon have played together a lot, we know each other, we get on well off the pitch. When you play together it does feel comfortable.
"We had some good seasons at Everton. Joleon moved on and has done well for himself since. But when you've played with someone 100 times or so, it makes it that little bit easier."
