AJAX are pondering a summer swoop for Celtic's on-loan Manchester City striker John Guidetti.

The Dutch giants wanted to take the Swede on a season-long loan before the start of the current campaign.

However, the 22-year-old frontman, who scored three goals against the Amsterdam outfit while on loan at deadly rivals Feyenoord in January 2012, knocked them back to move on a season-long temporary transfer at the Hoops.

Ronny Deila insists talks with Guidetti are still ongoing and the Parkhead boss would like him to agree to a permanent deal with the SPFL champions.

However, the international attacker has stalled and will be a free agent in June.

Ajax believe that has opened the door for them to top any personal terms offered by Celtic.

A Dutch source claimed: "We believe Celtic are thinking along the lines of £12,000-per-week.

"Ajax would be willing to triple that offer to take him to Amsterdam."

Guidetti's form has dipped alarmingly in the midst of all the transfer speculation.

He quickly became a fans' favourite in the east end of Glasgow when he netted 11 goals in a whirlwind 16-game spell, but he has found it difficult to get a regular place in Deila's recent line-ups.

The marksman has started only one game - the 1-0 win over Ross County - in the last five and was on the subs' bench again for the League Cup semi-final on Sunday although he came on for Leigh Griffiths in the 69th minute.

Guidetti hasn't scored a goal since he netted in the 4-0 Scottish Cup win over Championship leaders Hearts at Tynecastle on November 30.

However, according to Dutch sources, his lack of goals isn't likely to put off interest from Ajax boss Frank De Boer.
