Found a Dutch defensive midfielder Mees Hoedemakers who may fit the requirements, unfortunately again in the highlights his defensive ability not shown. The Italians in the previous post and this player have valuations of 1.2 million euros or less if Transfermkt can be believed.
Also an Australian box to box midfielder I'd recommend Boro have a look at is Angus Thurgate, a big improver last season, became more of a threat going forward and definitely handles the defensive side as well.
Choudhury looks he would be a top signing if he wants to come here, someone said he's rejected us twice though.
Here are two other defensive midfielders I've come across on database searches, both Italian. Pity that their short highlights don't include their defensive efforts, but they both look like they can control play in possession well.
Both also have been loaned extensively by their parent clubs, they might be interested in a permanent home.
Just a thought but....
General concensus is we need a lcb and at least two midfielders. And in reality the only ones we've been "linked" with are greaves, choudhary and hannibal. All British based players.
We also need at least one more striker, and we've been linked with hoppe, Henry, larsen to name but 3.
I wonder if there are possibilities of us finding a gem or two for the defensive and midfield positions from abroad too. Especially given the eredivisie link and we have only really been linked to 1 player from the Dutch league.
