David Martin has delivered a message to Millwall supporters on social media, after his decision to leave the club to join West Ham United.

The goalkeeper has signed for West Ham on a two-year contract, with the option to extend for a further year, after two years with Millwall.

Martin made ten Championship appearances for Millwall last season, conceding nine goals and keeping four clean sheets.

He also started in the FA Cup quarter-final with Brighton, but conceded two late goals and made a mistake for the injury-time equaliser, as Millwall lost on penalties.

The 33-year-old posted this message on his personal Twitter feed, thanking Millwall and wishing the club all the best for the future.

Millwall finished 21st in the Championship last season, four points above the relegation zone and will be looking to improve on that next season.

The Verdict:

Martin only made 15 appearances for Millwall throughout his two years at the club, but he was an important player for the team towards the end of last season.

It's a questionable decision for Martin to join West Ham at this stage of his career and he is unlikely to start over the experienced Lukasz Fabianski.

I'm sure Millwall fans won't appreciate him leaving to join their biggest rivals, but it is good of him to send a message to the club as he departs.
