My Best pre season vs a really bad team was 3 goals in about 4 mins.
I had a regen.
My best season one was by a guy named Anderson. A Brazilian regen. He was a Central defender and he was AWESOME. Infact his only stat apart from Finishing and Long shots that was below 10 was his Concentration.
He was 2m's tall (about 6 ft 8) Had 14 Accell and PAce, 20 Jumping, 17 Anticipation, 20 Heading. he was just so **** good and he held my back line for a number of years alone (Did have a bad injury streak at one stage though) but he scored a hattrick in 6 mins from the near post corner cheat (I say cheat because it is one) against Bayern Munich in the first knockout round of the CL He went on to score 39 goals in 30 games that season in the league.
That is also the last season I'd used it, It's just so unrealistic, but can be funny.
