Mackay left Vicarage Road in the summer giving Dyche the chance to cut his managerial teeth and the former Chesterfield defender has acquitted himself well, with a cash-strapped Watford side sitting 18th in the table.
The coffers will be boosted on Friday night when Tottenham make the short trip north and the Championship side are a 7/1 chance (Stan James £150 free bets) to claim a big scalp and book their place in the last sixteen of the competition.
Watford can have some confidence considering that Harry Redknapp will surely choose to rest his star players ahead of Tuesday’s Premier League clash against Wigan, with the likes of Gareth Bale, Luka Modric and Scott Parker set to be sidelined.
However, the Hornets have lost their last three Championship matches, the latest of which was a 3-0 reverse against Birmingham on Saturday. Perhaps the Tottenham reserve side will prove too strong considering there is strength in depth at White Hart Lane.
Redknapp’s side were comfortable 3-0 winners against an in-form Cheltenham team in the last round and we might see Emmanuel Adebayor get a run out considering the striker was ineligible for Sunday’s 3-2 defeat against Manchester City.
The visitors are a 1/2 chance (bet365 free bets) to book their place in the fifth round of the competition without too much fuss and it will be a chance for Steven Pienaar, Jake Livermore and Danny Rose to stake their claim on a place in the first team.
We can envisage an entertaining contest with a few goals flying in and the 5/6 (Sky Bet bookmakers) about three or more being scored looks the ticket.
