Sinclair, the fifth pundit to reveal his predictions for 2017/18, says Defoe's predatory play on the tight Vitality Stadium pitch could make the Cherries this season's surprise package.
Who will finish in the top four, and in what order?
1Manchester City. Full-backs are a huge part of Pep Guardiola's teams. They've recruited very well and strengthened at goalkeeper which hurt them last season.
2Chelsea. They were incredible last season but the 3-4-3 formation that worked so well will require tweaking due to the Blues not having the best squad for the Premier League. There is the added pressure of UEFA Champions League commitments this season.
3Manchester United. There is big pressure on record signing Romelu Lukaku, who will do well and add raw pace to the attack, but they still lack depth.
Dominic Solanke at Liverpool. He has had some great performances in the England side that won the FIFA Under-20 World Cup, as well as an impressive pre-season at his new club and, given the opportunities, he will shine.
