Chelsea defender Tomas Kalas' says playing away on-loan has improved him.
The defender is expected to sign permanently for Fulham this summer.
He told the London Evening Standard: “Playing for Fulham, and Middlesbrough last season, has helped me much more.
“For example, Rotherham may have been relegated this season, but I learnt how to approach a game like that, how professional you have to be on the pitch.
“I do weights after training now because I realised I can't be a defender weighing 70kg. I realised that when playing against Kenneth Zohore (the Cardiff striker who scored twice in the 2-2 draw against Fulham in February). That was a striker I struggled with physically."
