However, it is not certain that a loan move to Turkey will happen.

If it does, it would represent a blow to the former Spurs player, who joined Everton in attempt to revitalise his career.

Alli played his part in key results that helped Everton avoid Premier League relegation last season.

But Everton boss Frank Lampard has called on Alli to show more consistency in training. He has been used as a second-half substitute in both of the club's league defeats so far, against Chelsea and Aston Villa respectively.

Meanwhile, it is understood Everton are edging closer to concluding the signing of Paris St-Germain midfielder Idrissa Gueye.

Gueye, 32, left Everton to join PSG in 2019 for about £30m.

The two clubs have been in talks about a return to Goodison Park for the Senegal international since last month.
