It will be interesting to see how Alfie Mawson fares on his Swansea City debut.
The big centre-back, signed from Barnsley this summer, will have his hands full with Watford's physically imposing striker partnership of Troy Deeney and Odion Ighalo.
So far, however, the 22-year-old has looked comfortable - calm in possession and firm in his challenges.
