Sky Sports tennis pundit Barry Cowan offers up his charity bets for the World Tour Finals

Sky Sports tennis pundit Barry Cowan will be raising money for The Royal British Legion’s Poppy Appeal during the World Tour Finals.

Barry will be providing his predictions throughout the week of action with the proceeds going towards the cause, which supports the Armed Forces community.

Football League sponsor Sky Bet will also be contributing with their Twitter campaign #BidToRemember as they auction a range of signed, match-worn poppy shirts worn by players in this weekend’s Championship fixtures.

For Barry’s part, he’s tipping world no 1 Novak Djokovic to make it a hat-trick of titles and the O2 Arena by beating Roger Federer in the final – which is priced up at 9/2.

In his Sky Sports podcast preview, he said: "With 27 wins in a row indoors, Djokovic really is the favourite, not just because he’s world no 1, not just because he’s in great form but also because he’s in the easier group.

“I certainly expect him to come through his group and wrap up the season-ending world no 1 before the semi-finals and then go on and win the World Tour Finals again.

“The way Federer is playing, that certainly suggests he is the man to cause an upset but everything points to Novak.

“Therefore, I’m backing both Djokovic and Federer to win their groups, avoid each other in the semi-finals and then the no 1 and 2 players in the world to battle it out in the final, where Djokovic will win it, in three."
