Portugal coasted to a 4-0 win over New Zealand in St Petersburg and secured their place in the semi-finals of the Confederations Cup.

The win, however, came at a cost as Manchester City-bound midfielder Bernardo Silva was forced off with an ankle injury.

With hosts Russia losing 2-1 against Mexico in Kazan, Portugal progressed as Group A winners, while the All Whites finished bottom following a third straight defeat.

Captain Cristiano Ronaldo put Portugal ahead from the penalty spot on 33 minutes.

Bernardo Silva - who has joined City from Monaco for £43million - swiftly doubled the lead with a close-range finish, but in doing so landed awkwardly on his ankle and was taken off at half-time.

Forward Andre Silva wrapped up the comfortable victory with a fierce angled finish on 80 minutes and Nani added a fourth in stoppage time.

New Zealand, the OFC Nations Cup winners, had made a positive opening with Leeds forward Chris Wood seeing his shot saved.

Ronaldo rattled the crossbar before Ipswich defender Tommy Smith bundled over Danilo Pereira in the box following a corner - the Real Madrid icon stepped up to score his 75th international goal from the penalty spot.

It was soon 2-0 to the European champions when Bernardo Silva converted a low cross from Eliseu after 37 minutes.

However, the attacking midfielder turned his ankle as he landed ahead of a sliding challenge from Tom Doyle, which saw him replaced by Luis Pizzi after the break.

Just before half-time, Portugal forward Andre Silva lashed out at Michael Boxall after a tussle with the New Zealand defender, which left him with a torn shirt - but could easily have also resulted in a red card.

New Zealand almost pulled a goal back on the hour when Doyle's ball across the face of goal from the left found Wood at the far post, but Portugal goalkeeper Rui Patricio recovered to make a sliding block on the line.

Marinovic had produced a string of decent saves at the other end during the second half.

However, the All Whites keeper could do little when Silva, who AC Milan signed from Porto for £35million, darted into the right of the penalty area before crashing the ball into the top corner.

Valencia star Nani, who came on for Ronaldo, then added a fourth in stoppage time.

The former Manchester United man created space for himself with a clever step over before drilling home a low drive to seal Portugal's path to the Confederations Cup semi-finals.
