Celtic supporters need to keep an eye on a number of things this summer in Russia.

With the World Cup on the horizon, we take a look at five things that Celtic fans need to keep an eye on in Russia.
Tom Rogic

Rogic has just penned a new contract with Celtic, much to the delight of the Parkhead crowd.
Celtic fans can now watch without fear that Rogic could depart, and that must be good news.
Rogic looks set to play a key role for Australia, as the creative fulcrum of their team, and all Celtic supporters will be wishing him well.
Cristian Gamboa

Gamboa is in the Costa Rica squad, and this could be his last chance at salvaging his career at Celtic.
Brendan Rodgers hasn’t picked the right-back much, but in 2014 Gamboa was one of the stars in Costa Rica’s side, and another strong World Cup performance could push him back into the Celtic boss’s thinking.
Ashley Young

Manchester United have been heavily linked with a move for Kieran Tierney, but if Young performs for England then the pressure on the Red Devils to sign a left-back will be reduced.
Sardar Azmoun

The long-term Celtic target is in the Iran squad, and his country’s chances will rest on him hitting form.
If he does impress, it would not be a surprise to see the Bhoys move for the attacker in the summer, given their reported admiration of his talents.
Dedryck Boyata

Oft criticised Celtic defender Boyata is in the Belgium squad, and he has much to prove.
Whether Boyata will play in Russia remains to be seen, as he appears a reserve choice, but just making the Belgium team should be seen as an impressive achievement for the Bhoys centre-back.
