Mikel San Jose is confident Athletic Bilbao team-mate Aymeric Laporte will reject the advances of clubs in the Premier League during the off-season.
Laporte has developed into one of the most sought-after defenders in Europe since breaking into the first team at San Mames and is reported to be a target for both Manchester City and Manchester United.
Despite the Frenchman's contract containing a €50 million buyout clause, San Jose feel he realises he's at a great club that can continue to develop with a young, talented squad.
"I am confident that he will continue with us," the Spaniard told Onda Vasca. "If I have to get wet, I get wet but I guess in football you never know what can happen.
"A league like the Premier League is always making very high transfers and you never know, but I think [Aymeric] is very focused and very happy here.
"If I have to say something, I trust he will continue with us. He knows he's at a great club, in a great locker room and a great city to grow. In that sense, I'm calm."
