Celtic boss Brendan Rodgers could be looking at a Scotland after having been spotted at Hampden on Tuesday.
The manager was joined by assistant Chris Davies as Scotland defeated Israel 3-2 in the Nations League.
There are only a few players that Rodgers would be keeping an eye on.
Potential right-back problem being solved?
One player the manager could be looking at is Scotland’s Callum Paterson.
The right-back turned striker had an average game and wouldn’t have shown Rodgers too many qualities.
MORE CELTIC STORIES

The ex-Hearts man is well known to the Celtic support having been linked in the past.
Mikael Lustig is on the last year of his contract and may be on his way out of Parkhead.
Rodgers revisiting old ground
According to the Daily Record, Aberdeen rejected a bid from Celtic for Scott McKenna in the summer, so Rodgers may have been watching the defender once again.
However, the manager could still be keeping an eye on the 22-year-old.

Celtic will be without loan centre-back Filip Benkovic next season and fans are crying out for a permanent stopper.
Conceding two goals against Israel wouldn’t have done McKenna any favours.
Another player Celtic have been unsuccessfully chasing for years is Steven Fletcher. The 31-year-old came close to signing with Celtic in 2015.

With Leigh Griffiths being in and out the team, Rodgers could be looking elsewhere.
The target man has played 20 games in all competitions this season, scoring four. Not the run of form Celtic fans are hoping for in a new striker.
Planning for Red Bull opponent
The player being watched may not be a future signing at all.
Instead, the management duo could be watching a future opponent playing for Red Bull Salzburg – though fans may wish that he would be a future signing.

Israeli forward Moanes Dabour has already scored against The Bhoys this season.
However, as the final match of the campaign at Celtic Park is so important, Davies and Rodgers could be trying to get a head start.
The striker is the Europa League’s current top scorer and could end Celtic’s hopes of progression.
Nobody will know why the manager was at Hampden until the future, until then it’s anyone’s say.
