Arsenal defender Hector Bellerin set to sign new and improved four-year contract

Hector Bellerin will reportedly sign a new four-year deal with Arsenal after impressing the club's hierarchy with his performances this season.

According to the Mirror, the club is keen to tie down the young Spanish defender, who has a contract with the club until 2017 to a new long-term deal following some impressive displays for the Gunners thus far this campaign.

Bellerin has made the right-back spot his own after coming into the team following injury to first choice full-back Mathieu Debuchy. The French defender, who arrived from Newcastle United in the summer has suffered an injury plagued season and is currently out with a shoulder injury, which is his second spell on the sidelines after initially missing three months with an ankle injury.

The 19-year-old Spanish youth international has come through the youth ranks at Arsenal following his arrival from Barcelona's famed La Masia academy and was called into action due to injuries suffered by Debuchy.

He has not looked back since and put in some assured performances in the Premier League and Champions League making 19 appearances for the club in all competitions thus far this season. And this has convinced the club to give him a new deal that will keep him at the club until the summer of 2019.

This new deal for Bellerin could mean the end of the road for fellow right-back Carl Jenkinson, who is currently on loan with West Ham United.

The former Charlton defender has been outstanding for the Hammers this season and they are keen on making his loan move permanent and with Bellerin and Debuchy ahead of him in the pecking order at the Emirates Stadium, it is believed that Arsene Wenger will let him leave.

The report claims that interested clubs will have to pay Arsenal a fee in excess of £6m ($8.9m) to part with the England U21 defender.
