Celtic are reportedly in advanced talks with Cameron Carter-Vickers over a permanent move to Parkhead this summer, in what would be a big piece of business.

The Lowdown: Carter-Vickers excelling on loan

The American joined the Hoops on a temporary basis last summer, coming in on loan from Tottenham in order to enjoy more regular playing time.

Carter-Vickers' switch north of the border has been a match made in heaven, with the 24-year-old becoming a key part of Ange Postecoglou's defence in the Scottish Premiership.

The centre-back's future remains up in the air - a number of other clubs want to sign him this summer - but a promising update is now doing the rounds.

The Latest: Permanent move close?

According to SBI Soccer, an American source has revealed Celtic are now in 'advanced talks' to sign Carter-Vickers permanently at the end of the season, with Spurs still valuing him at £6million.

The report states that Wolves, Leicester City and Watford have all shown an interest, too, but the Hoops appear to be in pole position for his signature.

The Verdict: Huge news for Celtic

Carter-Vickers may already be part of Celtic's squad but clinching a permanent move for him this summer really would feel like a big signing, given his influence.

The USA international has been an increasingly colossal performer at the heart of the defence, averaging 3.2 aerial duel wins and an 89.8% pass completion rate in the Europa League this season, showing he is more than capable playing at a higher level.

At 24, he is primed to improve in the coming years, becoming an even more formidable player, and he could play a big part in Celtic's future, potentially then being sold for a hefty profit after some years of sustained success.
