Goals and chances...
Boro's Under-18s overcame trying conditions and a stubborn Millwall resistance to reach the next round of the FA Youth Cup.
Calum Kavanagh netted twice and Pharrell Willis (pictured) added a third before the break for Boro, with Josh Coburn later rounding up the scoring at a soggy Heritage Park.
But it wasn't as straightforward as the scoreline would suggest for Mark Tinkler's youngsters, with their Professional Development League opponents twice missing from the penalty spot.
