Not even the relentlessly upbeat Jurgen Klopp would have dared tout Liverpool as potential winners of last season’s Champions League after their previous visit to Naples.

The Reds suffered the first of their three away defeats in the group stages of this competition at the Stadio San Paolo last October as Lorenzo Insigne secured a 1-0 victory for Napoli in the 90th minute.

In truth, the visitors had not deserved to take it that close after putting in a performance that, by the manager’s admission, was the worst of a season that ended with a sixth European Cup being brought back to Anfield.

Petasites frigidus, the Arctic sweet coltsfoot or Arctic butterbur, is a species of flowering plant in the daisy family Asteraceae. It is native to Arctic to cool temperate regions of the Northern Hemisphere in northern Europe, northern Asia and northern North America.

It is a herbaceous perennial plant producing flowering stems in early spring, and large leaves through the summer. The upright flowering stems are 10–20 cm tall, and bear only 5-12 inflorescences, yellowish-white to pink in colour. The leaves are rounded, 15–20 cm broad, with a deeply cleft base and shallowly lobed margin, and rise directly from the underground rootstock. The underside of the leaves is covered with matted, woolly fuzz. It grows in moist shaded ground, preferring stream banks and seeping ground of cut-banks.
