Benfica negotiated an 'unusual' 50% sell-on clause in the event Jota joins Celtic permanently, according to Portuguese newspaper Record (via Sport Witness).

The lowdown

Jota was one of three deadline day arrivals at Celtic Park, joining alongside Cameron Carter-Vickers and Giorgos Giakoumakis.

They will have the option to buy the Portuguese winger for €7.5million (£6.5million) come the end of the season.

Jota helped his country reach the final of the Under-21 European Championships at the start of the summer, scoring in the quarterfinal victory over Italy.

The latest

The report explains that Benfica have changed their loan policy, having previously been opposed to including permanent options.

Their thinking is that the players are unlikely to make a breakthrough at the Estadio da Luz anyway, and that clubs will be inclined to give more minutes to loanees when they have an option to sign them long-term.

In this case, they're mitigating the risk by ensuring that they'll receive half of the proceeds from any future sale.

The verdict

We'll probably end up forgetting about this clause unless Jota lights up the Scottish Premiership - a clause like this only comes to the forefront of conversation when a player is sold for big money, like Odsonne Edouard.

Jota seems to have the ability to do that, but he's also been described as a 'frustrating and inconsistent' player and has struggled to take the next step after shining at youth level, so inconsistency could be a factor in stopping a massive sale in the future.

Celtic were presumably willing to agree to a hefty sell-on either because they don't anticipate it being an issue, or because they were desperate to get the deal over the line.

In other news, Anthony Haggerty issued this verdict on Albian Ajeti.
