Celtic defender Virgil van Dijk admits to being curious about whether he can cut the mustard at a higher level, but insists for now the Scottish champions will do just fine.
Van Dijk helped Celtic to their fourth consecutive Scottish Premiership title recently and is a key man under boss Ronny Deila.
The Dutchman's fine performances in the heart of Celtic's defence have seen him linked with a number of clubs, including English Premier League giants Arsenal.
But while the centre-back knows Scotland's top flight cannot be compared with those leagues in England and Germany, he does feel he can still improve at Celtic.
Van Dijk told the Algemeen Dagblad: "I'm focused on the present.

"Look, Scotland is of course no Bundesliga or Premier League.
"Every footballer, and I'm no different, wonders whether he can do it at a higher level.
"I have that confidence in myself, but at Celtic I am certainly not stopping learning, especially in European competitions", Van Dijk added.
The 23-year-old has so far made 56 appearances in all competitions for Celtic this season, chipping in with ten goals and five assists for his team-mates.
Van Dijk also picked up the Scottish League Cup with Celtic this term.
