Injury-plagued defender Yado Mambo has been invited back to train with Ebbsfleet United in pre-season.

The former Charlton player signed for the Fleet in February, having been kept out of the game for seven months by a serious knee problem.

Mambo made four starts for Steve Brown’s side – three in the league – but he pulled up in the 2-1 defeat at Boreham Wood on March 22 and didn’t feature again.

Brown said: "We know what Yado’s qualities are. But there are reservations from our perspective about that knee. We need to know, 100%, that we’re not signing him with an existing injury.

"He needs to show us a bit of faith, come back to pre-season and get through the friendlies. Yado can come back and train with us and if the knee proves fit and steady and he’s ready to play, then we can start discussing terms."

Brown also revealed that another knee injury victim, midfielder Michael West, could be back in action by the turn of the year.

West, who rejoined Ebbsfleet from Crewe Alexandra in January, damaged his cruciate ligaments playing at Whitehawk on March 15.

Brown said: "The estimated time is Christmas but it’s difficult with a long-term injury to put a time frame on it. We don’t know how he’s going to react when he starts his rehab."
