Question: How many teams did the Huddersfield Town loanee that replaced Paul Hayes play for? Passage:Brentford began the season with a disappointing 1–0 defeat at the hands of Walsall in the League Cup first round and hovered around mid-table in League One before coming into form in late October 2012. Summer forward signing Paul Hayes failed to produce regular goals and was replaced by Huddersfield Town loanee Jimmy Spencer, who in turn was replaced by Marcello Trotta and the Italian would remain with the Bees for the duration of the season on loan from West London rivals Fulham. Inspired by the form of attacking midfielder Harry Forrester, an unbeaten run of 9 wins and four draws in 13 matches between 23 October 2012 and 21 January 2013 firmly established the Bees as challengers for automatic promotion, rising as high as 2nd position in the table. Headway was also made in the FA Cup during the same period, with victories over Boreham Wood, Bradford City and Southend United setting up a fourth round tie versus West London neighbours Chelsea at Griffin Park on 27 January. In a match televised on ITV, Brentford twice took the lead through a quick-reaction Marcello Trotta finish and a Harry Forrester penalty, but the Premier League side ensured a replay when Fernando Torres pulled the score back to 2–2 with seven minutes remaining. Brentford were comfortably beaten 4–0 at Stamford Bridge in the replay and the match ended on a sour note when Chelsea defender David Luiz's "sickening" late shoulder charge on Bees midfielder Jake Reeves went unpunished and left Reeves concussed.
