West Ham have completed the signing of Arsenal striker Marouane Chamakh on a loan deal for the remainder of the season, but the young son of Hammers co-chairman David Sullivan is far from pleased.

Jack Sullivan has built up a sizeable Twitter following thanks to his inside information about a number of West Ham transfers, and was the first to tweet that the deal for Chamakh had been finalised.

But Sullivan junior, who was mascot for West Ham during last May's playoff final victory against Blackpool, was not a happy Hammer following the announcement and offered his apologies to supporters.

"I am very sorry about this news Chamakh has sign a 6 month loan deal! not my pick," he tweeted.

Sullivan certainly has every right to question a deal for a player who has scored just four times in the last two years, particularly with West Ham in need of a proven goalscorer.

Chamakh joined Arsenal from Bordeaux on a free transfer in the summer of 2010 and initially impressed for the Gunners with 11 goals before Christmas in his first season at the Emirates Stadium.

The 28-year-old has, however, been a huge flop ever since, and has not played a single game in the Premier League this season.
