Former Chelsea star Salomon Kalou is set to return to London as David Moyes is interested in signing the forward to bolster West Ham attack for the second half of the season.

The Hammers’ 2-0 defeat to Liverpool on Wednesday night left them lingering down in 17th and with a battle to avoid relegation on their hands.

Moyes desperately needs some firepower to help blast his flagging side up the table, with just goal difference keeping them above Bournemouth, who join Watford and Norwich in the drop zone.

German outlet Kicker report West Ham have now made an approach for Hertha Berlin striker Kalou as Krzysztof Piatek, who Moyes looked at earlier this month, closes in on a move to the Bundesliga side.

Kalou is best known in the UK for his six-year stint at Chelsea, during which he won the Premier League, the Champions League, the FA Cup four times, the League Cup and the Community Shield.

Moyes apparently sees the Ivory Coast international as the man to come in and give his faltering frontline a boost, with £45m Sebastian Haller so far failing to justify his mammoth price tag.
