That's how it's gone for us. It has taken Liam a couple of months to get up to speed and how we want to train – but I think we've seen a glimpse of how they are going to be."[111] Trotter then scored his first goal for the club, in a 3–1 win over Sheffield Wednesday on 26 April 2014.[112] His goal was voted the club's Goal of the Month for April and eventually the club's Goal of the Season.[113] However, his arrival at Bolton Wanderers was met with scepticism among supporters.[114] At the end of the 2013–14 season, having made sixteen appearances and scoring once for the side, on 12 May 2014, Bolton Wanderers confirmed that Trotter would join them on a three-year contract on 1 July after a successful loan spell at the end of the 2013–14 season.[115]

They have put their cash into this club over the years and no-one knows where it has gone. The club is in a bad financial state. They have the most right to be upset because their money has been misused. Of course we feel for them. They have been very understanding and have supported us through every single game. Since I have been back, this was probably the first time we've been booed. It is a credit to them. This isn't for us, we need to keep going for them."[133] Following a 3–1 loss against Brentford on 6 April 2016, Trotter caused controversy along with David Wheater when they made "an abusive finger gesture" on camera; which he apologised afterwards.[134] As a result, the pair was disciplined by the club.[135] Shortly after, Bolton Wanderers was relegated to League One after losing 4–1 to Derby County on 9 April 2016.[136] Soon after, Trotter was dropped from the first team and never played again for the rest of the season.[137] At the end of the 2015–16 season, Trotter went on to make sixteen appearances and scoring once for the season.
