With his Fenerbahce contract expiring in the summer, the veteran was approached by Barca, but decided to stay put.
Mithat Halis, a partner in the company that represents the defender, said: "Barcelona wanted to sign him (Skrtel) and were insisting on him because they needed a central defender that was a reliable alternative, but the player didn't agree because he did not want to be a substitute for Pique and Umtiti.
"I think he is a better centre-half than Clement Lenglet (Barcelona's eventual defensive signing). On the other hand, Martin Skrtel is happy in Istanbul and has an important role to play in Fenerbahçe. He did not want to be third choice at Barcelona.
"They (Barça reps) saw the player in the game between Slovakia and the Ukraine and appreciated again that Skrtel is the leader of his team, but Skrtel told us he wants to continue playing in Turkey."
