There are concerns about Mikel Merino's permanent move from Borussia Dortmund to Newcastle, but here's why Magpies fans should not fear.

The early form of Mikel Merino is becoming somewhat bittersweet for Newcastle United fans, with some concerned that his impressive performances will see other clubs swoop in for his signature.
Merino joined the Magpies on a season-long loan from Borussia Dortmund in the summer, but as the Chronicle reported at the time the North East side have an "obligation to buy".

The same newspaper later revealed that signing the 21-year-old on-loan cost Newcastle £2.7m, while they will pay a further £6.5m to sign the midfielder permanently should he make a certain amount of appearances - believed to be 20.
The concern seems to be whether because Merino has been in such fine form and in an inflated market currently, Dortmund could change their mind later on and instead tout the Spain Under-21 international around for a much higher price.
Yet the club themselves said in an official statement at the time: "A binding purchase option was agreed with the English club for the event that the player features in a certain number of competitive matches."
Newcastle United manager Rafa Benitez.
The word "binding" is the key to this and in fairness the Bundesliga outfit are already set to double the £4.5m they paid Osasuna for Merino in 2016, as reported by Goal, despite the fact the Spaniard started just two matches for them.
The only issue may arise if owner Mike Ashley refuses to stump up the cash, but in truth that is likely to be a breach of contract that would not be worth his time or money for such a relatively low fee.
Plus with what seems to be a sensible head on young shoulders, Merino knows he can thrive at St James' Park before possibly moving on in a few years. The presence of Rafa Benitez also helps, with the youngster telling the Independent of his manager:
"Of course it is better because of Rafa Benitez. I know Newcastle is a great club, a huge stadium, the crowd, everything, the staff and the people who work here but of course Rafa being at Newcastle helps, the language, the huge trainer he is, it makes the decision [to join] easier."
