Majority shareholder Farhad Moshiri has been asking probing questions after Everton failed to land several transfer targets, according to a report.

The Mirror has reported that Moshiri has insisted the club will not make the same mistakes again, and that heads will roll if the same problems occur in the future.

It is said that manager Ronald Koeman was left frustrated by what has been described as a scattergun last few days before the window closed, and new director of football Steve Walsh is under the spotlight after top targets were missed.

Moussa Sissoko made a £30million switch to Tottenham on deadline day, despite Everton thinking they had the deal sown up.

It is said Everton lingered over the deal, which allowed the north London club to capture the signing of the France international.

Sunderland defender Lamine Kone did not make a move to Goodison Park either, despite reports of a £17million bid.

Ronald Koeman also reportedly missed out on Zenit St Petersburg midfielder Axel Witsel and Arsenal’s £17.1million striker Lucas Perez.

Moshiri joined forces with Bill Kenwright on Merseyside, buying a 49.9% stake in the Premier League club in February, after selling his stake at Arsenal.

The Iranian gave Koeman a £100million war chest but less than half of that was spent, with the Dutchman signing eight players, including Yannick Bolasiea for a club record fee of £30 million.

In other Everton transfer news, this Premier League side will revive interest in the club’s midfielder in January.
