3. His Form is Extremely Consistent
While Hart has shown an alarming lack of consistency over the last few months, Forster has been a solid and reliable presence in goal throughout his career. Whether at Norwich in the Football League or Celtic in the Scottish Premier League, Forster has always kept clean sheets. His entire career record is 211 games and 106 clean sheets, meaning he doesn't concede in 50% of games. If it's impossible for the team to lose half the time then that's a pretty solid starting point to build on. In terms of saves, Forster's save percentage over the period 2010-2013 is an impressive 80.9% (compared to Hart's 74.4%, which has dropped to 63.2% for this season, placing him 16th in the Premier League goalkeeper table). Of course you could point to how Hart is competing in the higher standard English Premier League, but let's not forget that Rickie Lambert was able to carry his good League One scoring record up to the Championship, the Premiership, and an England career that features two goals in three games. Stepping up a level doesn't automatically mean a decline in quality of performance. Looking at the one competition in which both Forster and Hart competed together, the Champions League in the 2012-13 and 2013-14 seasons, Forster has kept 9 clean sheets in 20 games, conceding 19 goals, while Hart has kept 2 in 8 games, conceding 14 goals. This gives Forster a 45% clean sheet record to Hart's 25% and all this with Hart playing behind a much stronger defence.
