Another scare for Hearts as big striker Vladimir Voskoboinikov gets a header on target but it's straight at home keeper Jack Hamilton.

"Hearts are a shambles at the back," laments BBC Sportsound pundit Allan Preston. "They need to just focus on defending as a back four."

Jack Hamilton keeps Hearts in front with a marvellous stop, keeping out a powerful long range strike from Dimitri Kruglov.

Former Aberdeen captain and manager Willie Miller: "Kenny McLean is getting a bit of stick from the crowd, and rightly so. He has got to sort himself out. He is not happy with the close attention he is getting, but he has got to get on with it." 

It's not been the comfortable evening many might have predicted but Aberdeen have been growing in menace. They need to improve on the final ball though.

Jonny Hayes and Niall McGinn are growing into this game and look the men most likely to break down the visitors from their wide positions. The latter has a dig from distance but it's an easy save.

Handball. Big chance for Hearts to level.

"Hearts are finding this tie problematic. FC Infonet are playing three at the back, and the formation switches between 3-4-3 when they are attacking - which they've done with confidence and decisiveness - and 5-4-1 when they're defending. 

"There is little space for Hearts to operate in when they get to the final third. The players have often turned to the bench for advice, and there is a sense of Hearts still trying to find their way into this game. The away goal will sharpen their minds."

Niall McGinn gets forward to deliver a promising ball from out wide but it's confidently grasped by Fola keeper Thomas Hym.

Arnaud Djoum picks up the ball and sweeps it to Callum Paterson on the right flank. The full-back's cross finds Juanma, but his header is just wide.

Big anti-climax as Niall McGinn blazes a free-kick from a promising situation high and wide.

Ash Taylor is up for another corner as he meets a Niall McGinn delivery from a short one and he thuds a powerful header narrowly wide.

A mix-up in the Hearts defence gives veteran Infonet striker Vorskoboinikov a clear shot on goal, but his effort fails to trouble Jack Hamilton.  Let-off for the hosts.  

Ash Taylor lashes in as a corner is headed down by Jayden Stockley but the delivery from Jonny Hayes had curled out of play.

There are around 14,000 fans at Tynecastle tonight and they all got a fright as a sloppy moment from Callum Paterson allows Jevgeni Harin to race forward but the Estonian can only shoot wide. Big chance for the visitors...

"The visitors are composed, organised and look very efficient going forward. Aberdeen aren't at their sharpest but it's not down to that. Fola Esch have real quality. Suddenly everyone in attendance is starting to wonder how this will pan out."

Aberdeen's best moment so far as a good cross from Shay Logan is met at the back post by Jayden Stockley. The striker nods the ball down for Ryan Jack to have a pop but the captain's shot is blocked by a sliding defender.
