Mason Cotcher is training with Arsenal's senior squad.

The Sunderland striker, an England U17 international, has been on extended trials with Arsenal's U18 team.

And he was involved with the first teamers last week during the international break.

Jeorge Bird's Arsenal youth website is reporting Cotcher was given a special training kit including the letters TI, indicating trialist.

Cotcher is yet to make a senior debut, but did make Sunderland's bench for the FA Cup last season.
