Chelsea legend John Terry is stalling on a move to Spartak Moscow.

Terry, after leaving Aston Villa last summer, passed a Spartak medical on the weekend and can sign as a free transfer.

However, Sport-Express says the deal has run into difficulties.

Although Terry passed a medical, the deal is reportedly on hold as he and his family have concerns over moving to Russia.

But Spartak need an answer imminently as they desperately look to sign a defender before Friday's Russian Premier League registration deadline.
