Emirates Stadium defender moves across London to Upton Park.
Arsenal defender Carl Jenkinson has signed for West Ham United on loan for the rest of the season.
“It’s brilliant how it has turned out and I just want to thank the Gaffer and Mr Sullivan and Mr Gold because they put in a big push to get me here,” the Gunners youngster told the official Hammers website.
“I’m clearly seen as a big part of things here and hopefully I can prove my worth here because it is an important year for me.
The 22 year-old was bought by the Gunners as a potential heir to Bacary Sagna at right back, but although the Frenchman moved on to Manchester City on a free transfer last month, Jenkinson has not been deemed ready to assume his position.
Arsenal boss Arsene Wenger instead signed Mathieu Debuchy from Newcastle United as his senior option, and Calum Chambers from Southampton as his understudy, meaning appearances were likely to be very limited for Jenkinson.
Jenkinson’s career with the north London side may not yet be over, but the England international will need to have a big season at Upton Park under Sam Allardyce’s stead if he is to make the grade at Emirates Stadium.
