With the future of Glen Johnson still unknown, it is tipped that he will be leaving Anfield either in January or once his contract expires at the end of the current campaign with Roma keen on acquiring his services.

It is likely that Brendan Rodgers will want to cash in on the England right-back before losing him for free so that he can use his sale in the hopes of reinforcing his wing back role as well as his shaky defence.

So, if Johnson decides to depart during the upcoming transfer window, here are five possible replacements Rodgers should consider when preparing his team for the second half of the season.

Mattia de Sciglio

Name: Mattia de Sciglio

Age: 22

Position: Right / Left Back

Nationality: Italy

Club: AC Milan

Price: £10 - £15 million

Mattia de Sciglio should be a strong contender to replace Glen Johnson as he has already featured for the Italian national team on 17 occasions despite being only 22; he still has so much room for improvement and could very well become the next long term Liverpool right back.

He surely has the potential due to the fact that La Liga giants Real Madrid are also monitoring his situation so Brendan Rodgers may need to act fast with the January window closing in.

Dani Alves

Name: Dani Alves

Age: 31

Position: Right Back

Nationality: Brazil

Club: Barcelona

Price: £6 - £8 million

Although Dani Alves is already 31, he is still regarded as a quality right back with huge experience due to his trophy-filled years playing at Barcelona. He is sometimes criticised for his lack of defensive contributions, but he definitely makes up for that with his ability to attack, scoring and creating goals as though he was a winger.

Tipped to leave the Catalan giants in the near future, Liverpool face though competition from Arsenal, Manchester City, Manchester United, and Chelsea, all of whom are interested in adding him to their ranks for a cut-price deal.

Stephan Lichtsteiner

Name: Stephan Lichtsteiner

Age: 30

Position: Right Back

Nationality: Switzerland

Club: Juventus

Price: £8 - £10 million (asking price)

The experienced Stephan Lichtsteiner could be a great addition for Liverpool with his high work rate as well as his attacking and defensive qualities. He is a type of player who is never scared to get stuck in and make last ditch tackles and is often seen playing further up, sometimes like a winger.

Last season he managed to score two goals and provide eight in 24 starts for Juventus and is well on his way to replicating his form again this season, netting two and creating four in his nine starts.

Martin Montoya

Name: Martin Montoya

Age: 23

Position: Right / Left Back

Nationality: Spain

Club: Barcelona

Price: £16 million (buyout clause)

Another young right back Liverpool can consider is Barcelona's Martin Montoya, a player that has already proven his quality despite very limited playing time at the Camp Nou. Since Brendan Rodgers is still unsure who his usual wing back pairing are, the ability for him to play on both sides on the defence can be seen as a huge boost.

Having only made one appearance this season and just 12 last season, a possible switch to Anfield could mean that he is given a lot more regular first team opportunities, increasing his chances of a bigger role for his national side.

Nathaniel Clyne

Name: Nathaniel Clyne

Age: 23

Position: Right Back

Nationality: England

Club: Southampton

Price: £14 - £18 million

Having already bought three Southampton players during the summer, Liverpool may regret not signing Nathaniel Clyne as well because he is now currently seen as England's best right back. He featured in all 11 matches for the Saints this season and is enjoying his football as his team now sit in second place of the Premier League.

Due to his recent call-up to the national team as well as his rise in form, Ronald Koeman knows that interest in Clyne is on the rise as he is urging the club to offer him a new deal in order to make sure he stays. However, with Brendan Rodgers needing a quality right back, there is no better Englishman for the job.
