John Guidetti has revealed he told Celtic “I don’t think I owe you anything,” when they asked him to sign a new deal at Parkhead.
The Swedish striker spent a season-long loan in Glasgow during the 2014/15 season from Premier League giants Manchester City.
He netted 15 goals in his 35 games for the Scottish champions.
Guidetti got his Celts career off to a storming start in the first half of the season but struggled for form after the turn of the year before his loan spell fizzled out.
And he says the quality of the Scottish top flight played a big part in his decision to turn down a new contract.
He told the Times: “I went to Celtic, smash it the first half [of the season], and then they said, ‘John you have to sign a contract.’
“I said, ‘Listen, I don’t think I owe you anything’. Celtic’s a massive club but I like the big games. I don’t like — with all respect — Ross County away.
“When we won the league, we didn’t even celebrate, just walked round the pitch.”
Guidetti – who played under Norwegian boss Ronny Deila at Celtic – helped the side secure a Premiership title and League Cup triumph during his loan spell.
In the summer of 2015 the former Feyenoord hitman sealed his move to La Liga with Celta Vigo.
The Swede is set to take on Manchester United in the Europa League semi-finals tonight.
