Celtic, European champions over a half century ago, advanced from Group E as they fought back to clinch their first victory in Italy, with Frenchman Ntcham chipping oncoming goalkeeper Thomas Strakosha deep in stoppage time for the victor.
For them, Lazio "says goodbye to the Europa League", not because it's mathematically impossible for them to qualify, because they still can, but they will need a "miracle", needing to win their last two fixtures while hoping for a CFR Cluj collapse.
It is fantastic. Real credit to the lads.
"We needed a win, but we needed a performance".
PSV Eindhoven, the 1978 winners, suffered a humbling 4-1 defeat by Austrian team LASK Linz to slip to third in Group D behind their opponents and Sporting Lisbon, who won 2-0 at Rosenborg. That's the main thing.
Sporting now top Group D after a 2-0 win at hapless Rosenborg to reach nine points, two more than LASK and PSV.
We want to go on and win the group first and foremost and then we will park that for a bit and then carry on in the Europa League after Christmas.
"It's too early to say how far we can go in this competition but we can be a hard opponent for anyone".
Not for the first time this season, Forster, sidelined at Southampton for around 18 months, revealed his delight at being back at Celtic and involved in big European nights.
The Celtic boss believes that a disconnection had been formed between the club and the supporters after Rodgers left. There was real pride and it felt like the old days for me.
