The 26 year old, who is yet to win an international cap, believes he must move on from Shakhtar to give himself a better chance of securing a place in Dunga's Brazil squad.
"It's great to have a club like Chelsea interested in me," Teixeira told O Globo. "I always try to do my job well and play to my best.
"Shakhtar Donetsk are not very big in Brazil, and I think I may need to move on to stand out and earn a place in the squad. That's my goal for 2016."
