Chelsea are set to open new contract talks in the coming weeks with Victor Moses, according to a report.

The Sky Sports website claims that the Premier League leaders are keen to tie the 25-year-old to an extended deal following his stunning transformation this season.

It is said that Chelsea technical director Michael Emenalo has been impressed by Moses’ form in a new wing-back role and wants to reward him with an improved contract.

The Nigeria international signed a new contract at the start of 2015-16 before heading out on a season-long loan at West Ham but the deal is due to expire in 2019.

Sky report that Moses is a firm transfer target for Barcelona as they search for a new right-back to either replace or provide competition for Sergi Roberto and Aleix Vidal.

Chelsea’s desire to tie Moses down comes after a series of excellent performances for Antonio Conte’ side in a new wing-back role.

The 25-year-old has been a revelation since Conte switched to a 3-4-3 formation and has been a key figure in the London club’s climb to the league summit.

Moses scored the winner for Chelsea in their 2-1 win against Tottenham on Saturday, his fourth goal of the season and his third in the Premier League.

Football Insider verdict:

Chelsea appear to have been stung into action by two factors, Moses’ excellent form and the growing interest of Barcelona. The London club know that the Spanish giants have the cachet to lure the Nigeria international from Stamford Bridge, and they know that market forces dictate that Moses can earn a more lucrative salary than his current package. The 25-year-old barely had a look in during his first four years at Chelsea but has turned his career around after being handed a new role by a manager who clearly believes in him. Moses has a strong hand in negotiations but he should not overplay it. Being a first-team regular at a club on the up is not something he has experienced before, so he should stay put.
