It could be a question at the weekly pub quiz: which Scottish footballer is still involved in the Champions League?

The answer is Calum Mallace, a 25-year-old midfielder, who at midnight tonight our time is set to line-up alongside the likes of former England under-21 captain Nigel Reo-Coker when Montreal Impact take on Costa Rican side Alajuelense in the semi-final first leg.

Of course it is the Concacaf Champions League and not the Uefa version, but nevertheless Mallace is just 180 minutes away from a final in the most prestigious club competition in North American football.

Mallace - who was brought up in Torphichen, a village near Bathgate in West Lothian, until the age of nine - started for Montreal in their weekend MLS loss to DC United and looks set to keep his place in the starting XI.

A fortnight ago the Canadian side drew 1-1 with Mexicans Pachuca in the second leg of their quarter-final.

It meant that, after a 2-2 draw in the away leg, the Canadians went through on away goals to reach the last four of the competition for the first time in their history.

After spending the first few years of his life in Scotland, Mallace and his family moved to Minnesota due to his father's job and after being there for the rest of his school days there he then went to Marquette University in Milwaukee.

It was whilst at university he flourished as a midfielder and now he is in his fourth season at the professional outfit in Montreal.

Ahead of tonight's match in the Olympic Stadium, Mallace said: "The team are really enjoying the Champions League journey that we are on and we have played some good football.

"To go to Mexico in the first leg of the quarter-final and get a 2-2 draw really gave us a boost and now we cannot wait to give it a real go in the last four."

"When I entered the draft in 2012 I was not sure if I was going to get picked up by a big club, but thankfully Montreal took a chance on me and I have loved being here ever since," Mallace went on to explain in an accent which has retained a Scottish twang.

"I think when I first came in it took me a while to get used to professional football, but in the last couple of seasons I have felt more and more comfortable and as a squad here we are really close-knit.

"Sadly I haven't been back to Scotland too much in recent years due to my football schedule, but the rest of my family have and I often speak to relatives back over there."

The other semi-final sees Costa Ricans Herediano taking on Mexican outfit América.
