Man United kept their second clean sheet of the season in gameweek 2 which, combined with a favourable run of fixtures, is why they predicted to have the best defence over the coming 4 gameweeks.
Tottenham conceded twice in gameweek 2, but their next 2 home matches (Burnley and Swansea) are likely to prove far easier than Chelsea. They are expected to return to the good defensive form of last season in the next few weeks.
Chelsea are yet to keep a clean sheet this season, but ties against Everton (H) and Stoke (A) are likely to change that, but don't expect too much when Arsenal visit in gameweek 5!
The following 3 teams are predicted to concede the least goals in the next 4 Fantasy Premier League gameweeks (therefore most likely to keep clean sheets):
Brighton's defence have the easiest fixtures in the next 4 gameweeks without a single match against any of the 'big' teams. Home ties against West Brom and Newcastle (gameweeks 4 & 6) are most likely to yield clean sheets, but there is also potential when they visit Watford and Bournemouth.
Other than the visit of Man City in gameweek 5, Watford have a good run of fixtures including a home tie against newly-promoted Brighton (gw 3) and a gameweek 6 trip to Swansea who are yet to score in the league this season.
