Jenks is valued at around £8million but West Ham will be keen to negotiate that given the presence of such as of Hector Belerin, Calum Chambers and Mathieu Debuchy at the Emirates..
Apasr from the right back it appears the club will be looking hard at central defence where the club has been thin in the last couple of years.
Sullivan told the official website: “Our planning for strengthening the squad in the summer has been underway for some time
“I think we need goalscorers, a right back and maybe a central defender. The situation with Carl Jenkinson won’t be clear until the end of the season but we will have to sign a right back one way or another.
“We of course bought Cheik Kouyate to play in midfield and as a fourth choice centre half but two years in a row now we’ve been caught out in central defence so it might be that we look to strengthen in that area for next season.
“We have Doneil Henry of course and he won impressive reviews for his performances at Blackburn Rovers before getting injured. If he’s ready for the Premier League then he could get a chance, otherwise it might be that he goes out on loan again to gain more experience.
“If we do decide to buy, the challenge would be then trying to keep four central defenders happy but you do then have the cover for when you get injuries as we seem to have a habit of losing our centre halves for key parts of the season.”
