West Ham have made an improved £4million bid for Norwich City left-back Martin Olsson.

The 28-year-old Sweden international is one of several options being pursued by the Premier League side as they seek cover for the injured Aaron Cresswell.

Andrew Robertson of Hull, Manchester United's Cameron-Borthwick Jackson and Kieran Gibbs of Arsenal have also come under discussion.

The Hammers have already seen a £3m offer for Olsson rejected, because Norwich want £5m

However, a deal for Olsson could yet be reached this week though West Ham had a £3m bid turned down on Monday. Norwich want £5m for Olsson.

Olsson joined the Carrow Road club three years ago on a £2.5m transfer from Blackburn Rovers.

He has been capped 38 times for Sweden and played every minute of their three matches at Euro 2016 before they were eliminated at the group stage.
