Stephen Kenny has hinted he could try fitting both into his side.
Republic of Ireland manager Stephen Kenny has hinted he could start both Matt Doherty and captain Seamus Coleman in tonight's World Cup qualifying opener.
They kickoff their 2022 World Cup qualifying campaign away to Serbia tonight.
Kenny yesterday confirmed that Bournemouth keeper Mark Travers will make his competitive debut in goal - owing to Draren Randolph's injury.
However the make up of the rest of Kenny's starting lineup remains unclear.
Previous manager Mick McCarthy found it difficult to accomodate both Doherty and Coleman in the same lineup, with both players playing right back for their clubs.
But the current boss says it makes sense to have two of his best players on the pitch.
Kick-off at the Red Star Stadium is at 7.45.

Meanwhile at the same time, Group A favourites Portugal play host to Azerbaijan.
Wales also begin their qualification campaign tonight with a difficult Group E game away to Belgium.
However they will once again be without manager Ryan Giggs on the sidelines.
Giggs has been on leave since he was arrested on suspicion of assault last November.
