MOTD COMMENTATOR’S NOTES
Steve Wilson: “All the so-called golden football rules of seeking to maintain a stable squad and continuity in the manager’s seat have been scrunched up into a ball of so much rubbish, and lobbed unceremoniously into the Vicarage Road bin by Watford’s owning Pozzo family.
“One of Gino Pozzo’s first acts as owner in 2012 was to sack Sean Dyche, even though Watford had just finished in their highest league position for four years.
“Since then Gianfranco Zola, Beppe Samino, Oscar Garcia, Billy McKinlay, Slavisa Jokanovic, Quique Flores and now Walter Mazzari have been appointed Hornets’ boss.
“Meanwhile Dyche has found a home at Turf Moor – where they tend not to turf out their managers quite so regularly.
“The approach is different, the progress similar – so stand by for the first ever top flight meeting of Burnley and Watford.”
Burnley manager Sean Dyche on former club Watford: “It’s well-documented I’ve always had respect for the club.
“The situation, the business changed etc etc but I mean every word when I say I had a fantastic time there as player, youth coach, assistant manager and manager.
“Because business changes and you lose your job it doesn’t mean I hold any baggage at all, I certainly don’t. It’s a lot of water under the bridge and they’ve gone on to become a Premier League club so their model of working has worked for them.”
Watford head coach Walter Mazzarri: “We have shown that we can fight against anyone, but the real step forward I want to see is how we will behave against a club like Burnley.
“I haven’t been here long and I need to verify the progress of this team, and we will see on Monday night what the progress is.”
This is a big game for Burnley because the onus is on them to win it. Their attacking record is poor – they are in the bottom two for shots at goal and shots on target this season.
Watford generally play two up front, or a derivation of that, so if I am Dyche I am thinking we have got to go for it in this one. I think Burnley might nick it too.
