<text>  Arsenal defender Hector Bellerin is in line for a new contract following his breakthrough into the first-team. The Gunners want to tie the right-back down to a new long-term deal after a string of impressive displays in replacing the injured Mathieu Debuchy. Bellerins current deal expires in 2017, but he is now set to extend his stay at the Emirates Stadium. Hector Bellerin has been in the Arsenal first team of late, and will be rewarded with a contract extension . The young defender is now a key part of Arsene Wengers first team squad after some impressive displays . It is common practice at Arsenal to hand improved contracts to young players who make a consistent impact on the first-team. The 19-year-old has made 17 appearances for the club already this season, firmly establishing himself as a regular member of Arsene Wengers first-team squad. The news casts further doubt over Carl Jenkinsons career at the Emirates Stadium. With Mathieu Debuchy out injured, Bellerin has become the clubs reliable full back ahead of Calum Chambers . Bellerin started against Manchester United in the FA Cup, as Arsenal rely on him to fill in for Debuchy . The right-back is currently on loan at West Ham, with the east London club are keen to turn his deal permanent. And the emergence of Bellerin, as well as last summers capture of Debuchy, has pushed Jenkinson further down the pecking order at Arsenal. And the Gunners are likely to listen to offers for the full-back at the end of the season. Carl Jenkinson left, on loan at West Ham, will be offered to other clubs after falling down the pecking order .
