Former Gillingham striker Rory Donnelly scored a 40-yard header for his current club Glentoran last weekend.

The club tweeted: “We guarantee you’ve never seen a header like this before.”

Roy Carroll, in goal for Dungannon Swifts, came out of his box to head the ball clear but it only went as far as Donnelly, whose looping header from distance bounced once before ending up in the net.

“What a goal - unbelievable!” said the commentators as the ball hit the net. The video of the goal has gone viral this week, with over 100,000 views on the club's social media channel.

Donnelly was nursing an injury at the time but was alert enough to see the former Manchester United keeper - still playing at 43 - off his line and take his chance.

It was Donnelly’s second goal of the match against their struggling opponents in the Irish Premiership.

Commenting afterwards, Donnelly said: "I preferred the first goal, the second was just a header from long range that hit the back of the net!

Donnelly, now 29, spent two seasons with the Gills, scoring 12 goals in his 35 league starts.

Following his departure he went onto play three seasons at Cliftonville and is now in his second year at Glentoran, who were playing in the Europa League at the start of the campaign.
