Hearts legend John Robertson reckons Rangers will be in for a torrid time against FC Porto on Thursday evening if they don't up their game.

Steven Gerrard's men were held to a 1-1 draw by the Jambos at Tynecastle this afternoon and given the runaround by a particularly impressive Uche Ikpeazu.

The Gers were unable to hold onto their top spot in the Scottish Premiership as they didn't create enough chances to trouble Joel Pereira in the Hearts goal.

And Robertson, while working with BT Sport, fears they'll be in trouble if they don't improve in time for Thursday.

He said: "If Rangers play like they did today, they'll be in massive trouble in Porto.

"Porto won't be as laid back as Hearts were.

"Hearts got it right today, their wide men did well and Meshino took his goal well.

"It was a strong performance."

Ryotaro Meshino opened the scoring after a dismal piece of defending from James Tavernier allowed Jake Mulraney a one-on-one which was saved by Allan McGregor.

However the little Japanese midfielder was on hand to lob the rebound over the goalie.

Alfredo Morelos equalised from a corner before half-time.
