Reggie Bush has said that the Detroit Lions must work on building their chemistry.

The running back joined the NFC North side ahead of the 2013 NFL season, after coming to the end of his contract with the Miami Dolphins.

The 28-year-old told the Detroit Free Press: "As a team, when you have kind of have that mentality that no matter what the situation is, you can always overcome it and come out with a win. That type of chemistry.

"When offense scores a big touchdown and defense goes out there and gets a big stop or defense gets a turnover, offense goes out there and kind of answers with a touchdown. Something kind of like that.

"It's not something that happens overnight, from my experience in the past. It's something that you build. It's a culture, it's a mentality that's built from the off-season. It doesn't start in week one and week two."

Bush has 974 rushing yards and four touchdowns in 2013.
