Joey Barton is known to not mince his words, and on this occasion, the former Manchester City midfielder has questioned Everton's acquisition of Gylfi Sigurdsson.

The Iceland international was one of the Merseyside outfit's top targets during the summer transfer window.

It took time, but the Toffees managed to get a deal with Swansea City over the line, widely reported to cost in the region of £40m.

Sigurdsson was influential for the Welsh club last season, scoring nine goals and creating 13 assists in 38 Premier League outings.

However, for Everton, the midfielder has managed just one goal and one assist in nine appearances.

The 28-year-old is not the only player under-performing at Goodison Park, with the team overall failing to pick teams off.

Ronald Koeman's side have won just two of their seven top-flight fixtures, and they are yet to win in the Europa League group stage having lost one and drawn one.

While on talkSPORT, Barton spoke specifically about Sigurdsson, suggesting that the midfielder and Everton are not the right fit.

“Sigurdsson hasn’t hit the ground running, not much to my surprise. I never consider him that calibre of player. I think he needs to be a big player in a small team, but at Everton the team isn’t built around him so he can’t showcase the talent.”
