Jeremy Toljan has enjoyed a fairly comfortable start to life at Celtic since he joined on loan from Borussia Dortmund in January.
The right-back has been involved in three victories so far and the Bhoys are yet to concede a goal in the games he’s featured in.
He arrived at Parkhead with a decent reputation after playing for Hoffenheim and Dortmund, while he represented Germany all the way up to Under-21 level too.
The 24-year-old looks an immediate upgrade on Mikael Lustig in the full-back area and fans are happy with what they have seen so far.
But manager Brendan Rodgers will know a lot more about untested Toljan after Thursday night when Celtic host Valencia in the first leg of a Round of 32 Europa League tie.
Toljan is expected to take up his position at right-back and so far has shown he’s a speed machine that can join in with the attack well.
He’s set to get his toughest defensive examination to date in a Celtic shirt when he lines up against Denis Cheryshev.
Valencia have a number of dangerous attackers in their squad and Cheryshev is someone that should provide a threat.
The 28-year-old dazzler is a left-winger with tremendous pace and trickery, something he showed during Russia’s run to the World Cup quarter-finals last summer.
He’s going to be a serious threat to Celtic in wide areas if he’s on top of his game and he’s now beginning to settle following his summer switch to Valencia.
Celtic usually come unstuck against high-profile opponents in Europe, but they are hoping new signing Toljan can prove his value on Thursday and consolidate beliefs that’s he a top addition.
