Port Vale kept their slim Sky Bet League One survival hopes alive with an impressive away victory over fellow strugglers Peterborough, inspired by two stunning free-kicks from Ethon Archer.

The Valiants made a bright start and took the lead after just three minutes.

Ryan Croasdale opened the scoring with a low, controlled drive after being picked out by Onel Hernandez, setting the tone for an energetic display from Jon Brady's side, who made eight changes following their goalless draw with Barnsley.

Vale doubled their advantage in spectacular fashion on 16 minutes.

Archer stepped up to a free-kick from 25 yards and curled a sublime effort into the top corner, giving Peterborough goalkeeper Alex Bass no chance.

The hosts responded well and reduced the deficit just after the half-hour mark. James Dornelly capitalised on slack marking to sweep home Matthew Garbett’s corner in the 31st minute and bring the Posh back into the contest.

However, Vale reasserted control in the second half and restored their two-goal cushion in the 59th minute.

Archer repeated his earlier heroics with another outstanding dead-ball strike, once again finding the top corner and leaving Bass rooted to the spot.

Despite the valuable three points, third-from-bottom Port Vale remain 12 points adrift of safety with their survival chances extremely slim.

Peterborough, meanwhile, stay four points clear of the relegation zone, with four games of their League One campaign remaining.
