Maurico Pochettino has changed his full-backs today - with Serge Aurier and Danny Rose replacing Kieran Trippier and Ben Davies, while the third change from the side which lost to Juventus sees Victor Wanyama preferred to Eric Dier in the middle of the park.

It will be interesting to see how Bournemouth line up - they have tended to play three central defenders against the "big six" this season, but today's XI are capable of playing in two or three different formations - their only change is a like-for-like swap in attack as Lys Mousset replaces Joshua King as central striker Callum Wilson's main support.

Eddie Howe makes only one change to the side that drew 1-1 with Leicester last time.

France U21 international forward Lys Mousset replaces striker Joshua King, who drops to the bench.

Fit-again Jermain Defoe, Harry Arter and Jordon Ibe are also among the substitutes.

Bournemouth: Begovic, Francis, Cook, Gosling, Aké, Daniels, Wilson, Smith, Cook, Stanislas, Mousset.

Subs: Boruc, Surman, Arter, King, Defoe, Fraser, Ibe.

All the reaction from the Emirates to come, along with the build-up to Bournemouth v Tottenham.

Speaking of which...

At least Arsenal will go into the Milan game with some heart and spirit. If ever anyone needed a low-key game, it was Arsenal, and they just got it. They did enough, but they did no more than they had to. They had a couple of scares, especially with the penalty, but in the end they were comfortable winners.

Three points for Arsenal, but that perhaps doesn't tell the full story. Watford will reflect on what might have been.

The Emirates is emptying rapidly. Where are they all rushing off to?

Into the final minute...

Wahey! Sebastian Prodl, up from the back, swings a left peg at a volley that ends up somewhere near the top of the stand. Stick to defending.Three minutes added on...

Hans Segers is more impressive than Pele, surely?

A late flurry from Watford, with Richarlison having to be snuffed out by three red defenders. Nearly time for the fourth official's most important act of the day...

Jack Wilshere is charging around with the energy of a man who has been on the bench all day. He's involved in a move that sets Danny Welbeck free down the Arsenal left, with his shot palmed away by Orestis Karnezis

It feels like the sting has gone out of this one, like we're ticking down the clock until Arsenal take their three points. How different it was before Arsenal's second. or what might have been had Troy Deeney stuck that penalty.

Arsenal fans are singing "Deeney, what's the score?". Troy is still able to have a giggle with Ainsley Maitland-Niles, mind.

Karnezis should do much better. There's no real pace on Mkhitaryan's shot and it goes straight through him. OK, he's made two good saves, but that wasn't one of his best moments.

Bournemouth make just one change from the side which drew at Leicester as Lys Mousset replaces Joshua King in attack.

Spurs make three changes from the team beaten by Juventus - in come Serge Aurier, Victor Wanyama and Danny Rose.

Full team news to come.

Eventful day for Shkodran Mustafi. He scored the goal, now he's had to go off injured, replaced by Calum Chambers. It wasn't clear what was wrong with him, but Arsenal didn't mess around in pulling the trigger on the substitution.

Had Watford scored that penalty it would be a very different game. As it is, Arsenal can relax now. For the neutral, it would have made it a good finish. But it's the last thing Arsene Wenger would have wanted. I'll tell you one thing, the Arsenal fans celebrated that more than the two goals.

A neat example of how sport comes back to bite you. Troy Deeney probably doesn't regret those comments, mind. He was only saying what a lot think...
