The news of Ian Maatsen’s Chelsea release clause became known after his outstanding Dortmund debut.

A condition in Ian Maatsen’s new Chelsea contract that might see him permanently join Borussia Dortmund next summer was made public by the German tabloid BILD.

Maatsen only needed three days to complete his temporary move to Signal Iduna Park before he quickly earned a spot in Dortmund’s starting lineup.

Der BVB, who are now three points outside of the top four, defeated Bundesliga bottom-feeders Darmstadt 3-0 thanks to the 21-year-old’s immediate impact.

Maatsen played 90 minutes of football, making one tackle, one interception, and one blocked shot for just the second time this season.

In addition, he made two crucial passes, succeeded on two of his four long ball attempts, and created one major opportunity.

Maatsen is in position for a run of games in the starting lineup with Ramy Bensebaini away with Algeria for the Africa Cup of Nations and Julian Ryerson out.

German newspaper BILD has revealed a clause in Ian Maatsen’s new Chelsea contract which could see him join Borussia Dortmund permanently next summer.Maatsen wasted no time in earning a place in the Dortmund squad just three days after his temporary move to Signal Iduna Park.

The 21-year-old made an immediate impact in helping Edin Terzic’s side to a 3-0 win over Bundesliga bottom club Darmstadt and Der BVB are now three points clear of the top four.For only the second time this season, Maatsen played 90 minutes of football and returned one blocked shot, one interception and one save.He also made two key passes, completed two of four long ball attempts and created one big chance.

With Ramy Bensebain in Algeria for the Africa Cup of Nations and Julian Ryerson’s side, Maatsen is ready to do the series in the first team.He has already proven himself to be a reliable option at left back and it wasn’t long before talk of a possible permanent move to the club began to creep in.However, Dortmund may have to pay a big sum if they want to keep Maatsen permanently at Signal Iduna Park.

Before joining Die Schwarzgelben, the Netherlands international signed a contract extension with Chelsea that will keep him in the Premier League until 2026.Dortmund’s loan deal for Maatsen did not include an option to buy, but that should not greatly hinder negotiations over a possible agreement because the player’s new contract includes a release clause.BILD claim that the release clause is around £30 million and, contrary to previous reports, Dortmund do not have a right of first refusal on the player.

If the Bundesliga giants want the exciting talent permanently, they need to activate the release clause. However, it may not be that simple as several Premier League clubs are also interested in the left-back.Maatsen’s release clause is particularly attractive to Burnley, who saw a similar offer rejected last summer. If the Clarets retain their Premier League status this season, they will pose a tangible threat to Dortmund’s plans to keep Maatsen..
