Frank McAvennie expects West Ham to sign a left-back and a centre-half in the domestic window.

The former Irons and Celtic striker, speaking exclusively to Football Insider correspondent Dylan Childs, claimed that David Moyes will want to sign a new-left back to give Aaron Cresswell a “kick up the backside”.

Football Insider revealed on Monday that the Hammers are in talks to sign Watford defender Craig Dawson as their search for a new centre-half continues.

The 30-year-old still has three years remaining on his contract at Vicarage Road but is yet to feature for the Hornets in the Championship this season.

West Ham have until 16 October to complete a deal for the former West Brom man.

When asked by Football Insider if he expected the Irons to enter the domestic market in search of defenders, McAvennie said: “I think they need to sign another centre-half.

“When you look to the bench, that tells you what kind of team they are. You need like-for-like cover now, you need quality throughout the squad.

‘I think David Moyes will also bring in another left-sided player in, just to give Cresswell a kick up the backside.

‘It is the same as what Celtic have done with Greg Taylor. Give Cresswell some competition and something to think about.”

The London club have trimmed their wage bill significantly this week with big earners Jack Wilshere and Felipe Anderson leaving the club.
