Newcastle United boss Alan Pardew doesn't know how he'll handle his team selection this week.
Toon head to Ukraine for Thursday's Europa League last-32 second-leg clash against Metalist Kharkiv with the tie balanced at 0-0.
And then they have a crunch Premier League showdown with fellow strugglers Southampton at St James' Park on Sunday.
Boss Pards said: "We have to sit down and make sure we get team selection right.
"Southampton is a huge game and so is the second leg of this tie.
"We know there's a tail-off of energy from Thursday to Sunday."
