Manchester United rookie Josh King could be heading back to Old Trafford - after just two substitute appearances on loan at Borussia Monchengladbach.

The promising striker's move to Germany was initially held up in the summer - as talkSPORT revealed - as he required groin surgery.

Monchengladbach pursued the deal as they were keen to land King on loan but the 19-year-old has suffered another injury set-back.

It is understood King has damaged his groin again and both the German club and United are discussing the best course of action, with the Norway Under-21 starlet possibly heading back to Manchester.
