Charlton manager Nigel Adkins is potentially heading for a huge error as the club are reportedly keen on signing QPR right-back Todd Kane, after a report claimed that Portsmouth are not in for the defender.

What's the talk?

Charlton, Sunderland and Portsmouth were all named as clubs eyeing up Kane as a possible target for the upcoming transfer window. London Football News claimed all three teams were keen on the English full-back, who is expected to depart from QPR this summer after he lost his place in Mark Warburton's side to young defender Osman Kaykay earlier this season.

Since that report emerged, however, Portsmouth's interest in Kane has been rubbished. Hampshire Live has rejected the news that Portsmouth are a potential destination for Kane, leaving Charlton and Sunderland as the two teams in the race to sign the former Chelsea defender.

Heading for huge error

Nigel Adkins could be heading for a huge error if he opts to move for Kane, following the news of Portsmouth's lack of interest in the right-back. Kane has been a subpar performer in the Championship for the last three seasons, averaging a WhoScored rating of 6.52 or lower in each of the three campaigns for Hull and QPR. In the seasons just gone, Kane was displaced by Osman Kaykay and his last start in the Championship was in March as he played on the right wing.

Charlton are reportedly still in talks with Adam Matthews over a new deal at the club. The Welsh defender is out of contract at the end of the month and could leave on a free transfer unless Charlton are able to agree fresh terms with the right-back.

Matthews was a solid performer at right-back in League One, averaging a WhoScored rating of 6.72 in 18 starts in the position. He also started at centre-back, right wing-back and left-back, which proves that he offers value in multiple positions instead of just one.

Therefore, allowing Matthews to depart for nothing and then paying QPR a fee to sign Kane on a permanent deal to replace him could be a huge error by Charlton. Looking at the statistics of the two players, Matthews appears to be the better option and he is already in the door and acquainted with the rest of Adkins' squad. Charlton should be trying to pin Matthews down to an extended deal instead of signing Kane, allowing Sunderland a free run at the £7k-per-week defender.

Adkins has Chris Gunter in his squad to provide cover for his first-choice right-back. The experienced, ex-Reading, defender can play in a variety of roles and can offer competition to Matthews if his compatriot extends his stay with the club heading into next season.
