Middlesbrough have signed experienced Greek goalkeeper Dimitrios Konstantopoulos on a short-term contract until January.

The 34-year-old started his career with Greek side Kalamata and also played for Boro's Europa League opponents Egaleo before moving to England.
The Greek international has also played on loan at Swansea and Cardiff and has just finished a two-year spell at AEK Athens, where he made 39 appearances.
